Answer:
f(x)=f(x-2)
Step-by-step explanation:
-3.1x+7-7.4x=1.5x-6(x-3/2)
- 10.5x + 7 = 1.5x - 6x + 9
6x = 7 - 9
6x = - 2
x = - 1/3
(x) =
let y = f(x), then rearrange making x the subject
y = ( multiply both sides by (x - 2 ))
y(x - 2 ) = 3x (distribute )
xy - 2y = 3x ( subtract 3x and add 2y to both sides )
xy - 3x = 2y (factor out x on left side )
x(y - 3 ) = 2y ( divide both sides by (y - 3) )
x =
change y to x for inverse function
(x) =
