Answer:
see explanation
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y =
x + 4 ( multiply through by 2 to clear the fraction )
2y = x + 8 ( subtract 8 from both sides )
2y - 8 = x
Change y back into terms of x with x =
(x) , then
(x ) = 2x - 8
(4) = 2(4) - 8 = 8 - 8 = 0
Answer:
x^2-4x-12
Step-by-step explanation:
(x-6)(x+2)=x^2-6x+2x-12=x^2-4x-12
ANSWER
