Answer:
Step-by-step explanation:
we have
we know that
The function composition is equal to
(r ∘ s )(x) = r(s(x))
In the function r(x) substitute the variable x by the function s(x)
so
For x=3
substitute the value of x=3 in the function composition
A*2 + b* = c*2
(9)*2 + (8)*2
81+64= 145
145=c*2
12.04=c
