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
That you have an exponential function. These functions are typical for certain practical problems, such as population growth, or radioactive decay (with a negative exponent in this case).
The base of 1 is not used for exponential functions because it does not produce varied growth rates. An exponential function with a base of 1 would result in a constant value (1), regardless of the exponent, failing to demonstrate the characteristic rapid growth or decay associated with true exponential behavior. Therefore, bases greater than 1 (for growth) or between 0 and 1 (for decay) are required to reflect the dynamic nature of exponential functions.
The graph of a linear function is a line with a constant slope. The graph of an exponential function is a curve with a non-constant slope. The slope of a given curve at a specified point is the derivative evaluated at that point.
No, the equation ( y = 1x ) is not an exponential function; it represents a linear function. In this equation, ( y ) is directly proportional to ( x ), resulting in a straight line when graphed. An exponential function typically has the form ( y = a \cdot b^x ), where ( b ) is a constant greater than zero and not equal to one.

"The base of the exponent" doesn't make sense; base and exponent are two different parts of an exponential function. To be an exponential function, the variable must be in the exponent. Assuming the base is positive:* If the base is greater than 1, the function increases. * If the base is 1, you have a constant function. * If the base is less than 1, the function decreases.
The inverse function of the exponential is the logarithm.
Dentition, the numbering used for teeth, has nothing to do with the exponential function!
The exponential function describes a quantity that grows or decays at a constant proportional rate. It is typically written as f(x) = a^x, where 'a' is the base and 'x' is the exponent. For example, if we have f(x) = 2^x, each time x increases by 1, the function doubles, showing exponential growth.
The only non-exponential function that has this property would be a function that has the constant value of zero.

Power functions are functions of the form f(x) = ax^n, where a and n are constants and n is a real number. Exponential functions are functions of the form f(x) = a^x, where a is a constant and x is a real number. The key difference is that in power functions, the variable x is raised to a constant exponent, while in exponential functions, a constant base is raised to the variable x. Additionally, exponential functions grow at a faster rate compared to power functions as x increases.
The base of 1 is not used for exponential functions because it does not produce varied growth rates. An exponential function with a base of 1 would result in a constant value (1), regardless of the exponent, failing to demonstrate the characteristic rapid growth or decay associated with true exponential behavior. Therefore, bases greater than 1 (for growth) or between 0 and 1 (for decay) are required to reflect the dynamic nature of exponential functions.
It is not enough to look at the base. This is because a^x is the same as (1/a)^-x : the key is therefore a combination of the base and the sign of the exponent.0 < base < 1, exponent < 0 : growth0 < base < 1, exponent > 0 : decaybase > 1, exponent < 0 : decaybase > 1, exponent > 0 : growth.
