Question

Which of the following is not an example of a parent function? A. y = x B.y=2x^3 C.y=1/x D.y=2^x

Answer 1

Answer:

B.$y=2x^3$

Step-by-step explanation:

A. y = x

Given a linear function. There is no number added or subtracted with x. also the number is no multiplied with x. So this is a parent function

B.$y=2x^3$

Here 2 is multiplied with $x^3$. so there will be stretch or compression on graph. The parent function for $y=2x^3$ is $y=x^3$

This is not an example of parent function

C.$y=\frac{1}{x}$

There is no number attached with x. so this is a parent rational function.

D.$y=2^x$

2^x is an exponential function. It is an example of parent function.

Answer 2

C, IS THE FINAL ANSWER
