A power function has the equation f(x)=x^a while an exponential function has the equation f(x)=a^x. In a power function, x is brought to the power of the variable. In an exponential function, the variable is brought to the power x.

What is the difference between a line graph and a linear equation?
A linear equation, when plotted, must be a straight line. Such a restriction does not apply to a line graph.y = ax2 + bx +c, where a is non-zero gives a line graph in the shape of a parabola. It is a quadratic graph, not linear. Similarly, there are line graphs for other polynomials, power or exponential functions, logarithmic or trigonometric functions, or any combination of them.
How can you identify exponential function from its graph?
The exponential function - if it has a positive exponent - will grow quickly towards positive values of "x". Actually, for small coefficients, it may also grow slowly at first, but it will grow all the time. At first sight, such a function can easily be confused with other growing (and quickly-growing) functions, such as a power function.
What is the formula for exponential decay?
y=a(1-r) to the t power
What is 16807 in exponential form?
It is: 7 to the power of 5 = 16807
How do you know if an equation is exponential?
Basically, in an exponential expression (or equation) you have the independent variable in the exponent. For example: 5 times 10x The general form of an exponential function can be written as: abx or: aekx where a, b, and k are constants, and e is approximately 2.718. Note that just having a power doesn't mean you have an exponential equation. For example, in x3 the variable does NOT appear in the exponent, so it is not an exponential expression.
What the difference between an exponential equation and a power equation?
y = ax, where a is some constant, is an exponential function in x y = xa, where a is some constant, is a power function in x If a > 1 then the exponential will be greater than the power for x > a
What has the author Albert A Bartlett written?
Albert A Bartlett has written: 'The essential exponential!' -- subject(s): Overpopulation, Power resources, Energy consumption, Exponential functions
What are some careers that use logarithms and exponentials?
Careers that use exponential functions include psychologists, forensic scientists, engineers and chemists. Exponential functions are functions where the base is a constant and the power is variable.
What is the difference between PCC panel and PDB panel?
There is no difference between PCC ( Power Control Centre) and PDB (Power Distribution Board). Although they have different names, but their functions are same i.e. controlling power feeders.
The difference between an exponential number and a power of 10?
Exponential numbers are in the form ax where a and x are real numbers. A power of 10 is any number in the form 10x. By definition this is an exponential number. If by "an exponential number" you mean THE exponential number, e, then the difference lies in the value of the base. e is a transcendental number (just like pi) with a value of approximately 2.71818182859045235... Just like pi, this decimal theoretically does not terminate and does not repeat i.e. goes on for an infinite number of places. e is known as the "natural base" because it appears in many natural structures from logarithms to compound interest to complex numbers.

What is difference between nonlinear equation and transcendental equation?
A polynomial equation of order >1 that is, where the power of the variable is greater than 1 is a non linear function. A transcendental function is one that cannot be expressed as a finite number of algebaraic operations (addition, multiplication, roots). The exponential and trigonometric functions (and their inverses) are examples.
What is the difference between a power functions and a polynomial functions?
A power function is of the form xa where a is a real number. A polynomial function is of the form anxn + an-1xn-1 + ... + a1x + a0 for some positive integer n, and all the ai are real constants.
What is 8 to the 2nd power in exponential form?
8², that is the exponential form. :)
When would you use a power function and when would you use a exponential function?
Both of these functions are found to represent physical events in nature. A common form of the power function would be the parabola (power of 2). One example would be calculating distance traveled of an object with constant acceleration. d = V0*t + (a/2)*t². The exponential function describes many things, such as exponential decay: like the voltage change in a capacitor & radioactive element decay. Also exponential growth (such as compound interest growth).
What the difference between process piping and power piping?
What the difference between process piping and power piping?
What are the examples of real life situation in exponential function with concrete examples?
Exponential functions look somewhat similar to functions you have seen before, in that they involve exponents, but there is a big difference, in that the variable is now the power, rather than the base. Previously, you have dealt with such functions as f(x) = x2, where the variable xwas the base and the number 2 was the power. In the case of exponentials, you will be dealing with functions such as g(x) = 2x, where the base is the fixed number, and the power is the variable.Example:-Q: A bank account balance, b, for an account starting with s dollars, earning an annual interest rate, r, and left untouched for nyears can be calculated as (an exponential growth formula). Find a bank account balance to the nearest dollar, if the account starts with $100, has an annual rate of 4%, and the money left in the account for 12 years.A: b= s(1+r) xb= 100(1+0.04)12b= $160
