we know that a function composed of it's inverse leaves x
basically
(f o f⁻¹)(x)=x
so
(f o f⁻¹)(4)=4
answer is C

hi there!
step-by-step explanation:
a roof pitch is basically for every inch rise there is 12 inches run.
the height of the roof is also known as the rafter.
formula: rafter^2 = rise^2 + run^2
rafter^2 = 5^2 + 12^2
rafter^2 = 25 + 144
rafter ^2 = 169"^2
the height of the roof from the lowest point to the highest point is 169"^2.
hope this : )
