    Answer:

    g(f(2)) = 9

    Step-by-step explanation:

    Evaluate f(2) and substitute the value obtained into g(x)

    f(2) = 2 + 1 = 3 , then

    g(3) = 3² = 9

    Answer:

    9

    Step-by-step explanation:

    f(x)=x+1……..(i)

    g(x)= x^2……( ii ).

    gf(2)……..(III)

    substitute f( 2) to ……(I)

    f(2)=2+1

    f(2)=3

    gx=gf(2)

    gf(2)= 3^2

    =9
