Question

PLEASE HELP!!!!

Answer 1

Answer and Step-by-step explanation: Power Functions are of the form:

$f(x)=ax^{b}$

where a is scaling factor, which means, it moves the values of $x^{b}$ up or down;

and b is exponent or power, which determines the rate of growth or decay of the function.

The difference between exponential and power functions, is that in power functions, a variable base is elevated to a fixed exponent.

For that reason, Equations:

A. $f(x)=2^{4\sqrt{x} }$

B. $f(x)=\frac{\pi}{x}$

C. $f(x)=2.3^{x}$

D. $f(x)=2^{3\sqrt{x} }$

are NOT power functions.
