(x) =
Step-by-step explanation:
let d(x) = y and rearrange making x the subject, that is

2x = y + 4 ( divide both sides by 2 )
x =
Change y back into terms of x, so
(x ) =
Answer:
Just a little puppy
hope this helped
Step-by-step explanation:
Easy peasy
just subsitute I(x) for the x in the h(x) so
h(I(s))=-(2s+3)^2-4
distribute and simplify
h(I(s))=-(4s^2+12s+9)-4
h(I(s))=-4s^2-12s-9-4
h(I(s))=-4s^2-12s-13
