Question

Which set contains the range values for f(x) = 12-3x given the domain (-5,-1,8)?

Answer 1

Answer:

range={27,15,12}

Step-by-step explanation:

f(x)=12-3x

let x= -5

f(5)=12-3*-5

f(5)=12+15

f(5)= 27

let x= -1

f(-1)=12-3* -1. [-3*-1=+3]

f(-1)=12+3

f(-1)=15

let x=8

f(8)=12-3*8

f(8)=12-24

f(8)=12
