Question

F(x)=2^4xf(x)=2^x+3f(x)=2^x-2f(x)=2^xwhich of these is an exponential parent function

Answer 1

A parent function is the simpliest function of a family of functions that can be written as :

`f(x)=a^x`

Where a is a constant

and

x is the independent variable

From the choices, the only function that is in simplies form is

Choice D. f(x) = 2^x

The other functions are just the transformations of the parent function.
