Question

Given the parent functions f(x) = 5x − 1 and g(x) = 3x − 9, what is g(x) − f(x)?

g(x) − f(x) = 3x − 8 − 5x

g(x) − f(x) = 3x − 10 − 5x

g(x) − f(x) = −2x − 8 − 3x

g(x) − f(x) = −2x − 10 − 3x

Answer 1

i think its b but im not surure

Answer 2

substitute f(x) by 5x − 1 and g(x) by 3x − 9
3x-9 - (5x-1)=
3x-9-5x+1=
-2x-8 .A

Answer 3

oh..i forgot the parenthesis. ty :)
