A __________ function takes the exponential function's output and returns the exponential function's input.
No. The inverse of an exponential function is a logarithmic function.
If the question is, Is y = x4 an exponential function ? then the answer is no.An exponential function is one where the variable appears as an exponent.So, y = 4x is an exponential function.
The only non-exponential function that has this property would be a function that has the constant value of zero.
Logarithmic Function
Periodicity is not a characteristic.
A __________ function takes the exponential function's output and returns the exponential function's input.
No. The inverse of an exponential function is a logarithmic function.

Exponential relationship!
If the question is, Is y = x4 an exponential function ? then the answer is no.An exponential function is one where the variable appears as an exponent.So, y = 4x is an exponential function.
If y is an exponential function of x then x is a logarithmic function of y - so to change from an exponential function to a logarithmic function, change the subject of the function from one variable to the other.
fundamental difference between a polynomial function and an exponential function?
No, an function only contains a certain amount of vertices; leaving a logarithmic function to NOT be the inverse of an exponential function.
"The" exponential function is ex. A more general exponential function is any function of the form AeBx, for any non-xero constants "A" and "B". Alternately, Any function of the form CDx (for constants "C" and "D") would also be considered an exponential function. You can change from one form to the other.
Domain of the logarithm function is the positive real numbers. Domain of exponential function is the real numbers.
