Answer:

(a) 21

(b) 81

(c) (fog)x=(x+5)^2=x^2+10x+25                  

Step-by-step explanation:

We have given the function f(x)=x^2\ and g(x)=x+5

(a) We have to write the expression for given composition

g(f(4))

Now first we find f(4)

So f(4) = 4^2=16

So g(f(4))=g(16)=16+5=21

(b) f(g(4))

Now first we find g(4)

So g(4) = 4+5=9

So f(g(4))=f(9)=9^2=81

(fog)x=(x+5)^2=x^2+10x+25
