Question

Guided Practice

Find the range of the function rule y=5x−2 for the domain.

{−1/2, 1/4, 2/5}

A.
{−1/2, 3 1/4, 4}

B.
{3/10, 9/20, 12/25}

C.
{− 4 1/2, −3/4, 0}

Answer 1

C

Explanation:

if you put in the values (-1/2, 1/4, 2/5) in the function, it gives the answers in option C

Answer 2

C.

{− 4 1/2, −3/4, 0}

Explanation:

domain

-1/2;1/4; 2/5

range

-5 1/2; (5/4-2);0

{-1/2, 1/4, 2/5}

take the derivative of the equation 4 times. f 4 (x)=0.
