Given f(x)=7-2x find f (x+5)
I'm not sure how to approach this problem.
I have done this so far:
F(x+5) = 7-2x
F(x+5)=7-2(x+5)
F(x+5)=7-(2x+10)
Not sure if this is right and what to do next.

1. f(x)=7-2x

In f(x+5) you have replaced the x with x+5, so do the same thing on the right side

f(x+5) = 7 - 2(x+5)
= 7 - 2x - 10
= -3 - 2x <-----> same as 7-(2x+10) , you had it
