    first, evaluate the g(-3) because the oder of operations states that we carry out operations from innner to outer regarding brackets and parentheses. after G(-3) is evaluated, we get -2, because -3 + 1= -2. now we will use this result to solve f(x). So f(-2)= (-2)2 + 5, which results in 1. So the answer is 1.

    It all reduces to F(g(x))=2(x+1)+5=2x+7

    x= -3, so 2*(-3)+7=-6+7=1

    1 is the answer

    f[g(- 3)] = f[-3 + 1] = f[- 2] = 2 * (- 2) + 5 = 1
