What is the logarithmic function and exponential function?
The exponential function is e to the power x, where "x" is the variable, and "e" is approximately 2.718. (Instead of "e", some other number, greater than 1, may also be used - this might still be considered "an" exponential function.) The logarithmic function is the inverse function (the inverse of the exponential function).The exponential function, is the power function. In its simplest form, m^x is 1 (NOT x) multiplied by m x times. That is m^x = m*m*m*...*m where there are x lots of m.m is the base and x is the exponent (or power or index). The laws of indices allow the definition to be extended to negative, rational, irrational and even complex values for both m and x.There is a special value of m, the Euler number, e, which is a transcendental number which is approx 2.71828... [e is to calculus what pi is to geometry]. Although all functions of the form y = m^x are exponential functions, "the" exponential function is y = e^x.Finally, if y = e^x then x = ln(y): so x is the natural logarithm of y to the base e. As with the exponential functions, the logarithmic function function can have any positive base, but e and 10 are the commonly used one. Log(x), without any qualifying feature, is used to represent log to the base 10 while logx where is a suffixed number, is log to the base b.
How are exponential functions characterized?
An exponential function is any function of the form AeBx, where A and B can be any constant, and "e" is approximately 2.718. Such a function can also be written in the form ACx, where "C" is some other constant, used as the base instead of the number "e".
Which situation would not be modeled by exponential function?
There are lots of situations that are not modelled by exponential functions. A simple example is when something increases linearly. For example, assuming you have a fixed daily income, and save all of it, the amount of money you have is directly proportional to the number of days worked. No exponential function there, whatsoever.There are lots of situations that are not modelled by exponential functions. A simple example is when something increases linearly.

Is an exponential function linear?
No. An exponential function is not linear. A very easy way to understand what is and what is not a linear function is in the word, "linear function." A linear function, when graphed, must form a straight line.P.S. The basic formula for any linear function is y=mx+b. No matter what number you put in for the m and b variables, you will always make a linear function.
A logarithmic function is the same as an exponential function?
Apex: false A logarithmic function is not the same as an exponential function, but they are closely related. Logarithmic functions are the inverses of their respective exponential functions. For the function y=ln(x), its inverse is x=ey For the function y=log3(x), its inverse is x=3y For the function y=4x, its inverse is x=log4(y) For the function y=ln(x-2), its inverse is x=ey+2 By using the properties of logarithms, especially the fact that a number raised to a logarithm of base itself equals the argument of the logarithm: aloga(b)=b you can see that an exponential function with x as the independent variable of the form y=f(x) can be transformed into a function with y as the independent variable, x=f(y), by making it a logarithmic function. For a generalization: y=ax transforms to x=loga(y) and vice-versa Graphically, the logarithmic function is the corresponding exponential function reflected by the line y = x.
Can a exponential function be a negative number?
Well -x^3/4 would be exponential
How do you write the standard number -75.116 in exponential notation?
Negative numbers cannot be written in exponential notation. The rules require the number to be between 1.0-9.9.
Can an exponential decay model have negative y values?
An exponential function can have negative y-values. However, a real-world exponential decay model will never have negative values. Think of it this way... If you divide a positive number by 2 (or take half of it) and then divide that next number by 2, you will never reach or go below 0. For Example: 20, 10, 5, 2.5, 1.25, 0.625, 0.3125, etc. (Each number is half of the number before it.)
Why radioactivity is exponential?
The number of atoms that decay in a certain time is proportional to the amount of substance left. This naturally leads to the exponential function. The mathematical explanation - one that requires some basic calculus - is that the only function that is its own derivative (or proportional to its derivative) is the exponential function (or a slight variation of the exponential function).
When is an exponential expression completely simplified?
when there is no negative exponentswhen there is a minimal number of bases~
In a medical experiment the number of bacteria is halved every hour. What type of function represents this pattern?
Exponential Decay - Apex
The base of an exponential function can only be a positive number?
true
exponential function?
Involves the function b^x where base ,b, is a positive number other than 1.

Can the base of an exponential function be a negative number?
Yes, but remember that 2 negatives is a positive. so -2 to the 2nd power would be 4, but -2 to the 3rd power would be -8.
Example of exponential function?
Any function of the form aebx - for non-zero a and b - is exponential. For examples, just replace "a" and "b" with any non-zero number. Equivalently, any function of the form cdx - once again, for non-zero c and d - is exponential. Here, too, you can replace c and d with any number to get examples.
