Question

PLEASE HELP ME ASAP(WORTH 30 POINTS). If the domain is {0, 2, -6}, what is the range of y = -2x + 3?

Answer 1

Range = {3, -1, 15}

Explanation:

Domain = {0,2,-6}

function : y= -2x + 3

We replace the value of x with domain,

when x = 0

y = -2 × 0 + 3

y = 3

When x = 2

y = -2 × 2 + 3

y = -1

When x = -6

y = -2 × -6 + 3

y= 12 + 3

y = 15
