Question

PLEASE HELP!!!!

consider the equation below. which are NOT power functions? select all that apply
A. f(x)=2^4√ x

B. f(x)=pi/x

C. f(x)=2*3^x

D. f(x)=√2/^3 √ x

E. f(x)=2(x-3)^1/2

F. f(x)=x^2+2x-6

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√(x) )`

B.
`f(x)=(\pi)/(x)`

C.
`f(x)=2.3^(x)`

D.
`f(x)=2^(3√(x) )`

are NOT power functions.
