If h(x) = x – 7 and g(x) = x2, which expression is equivalent to (g ▪ h) (5)? (5 – 7)2 (5)2 – 7 (5)2(5 – 7) (5 – 7)x2

The correct answer is (5 - 7)^2

Step-by-step explanation:

To find this, start with the outermost equation g(x).

g(x) = x^2

Now put the next equation (h(x)) in for x in this equation.

(G ▪ H)(x) = (x - 7)^2

Now, put the number in for x in the equation given.

(G ▪ H)(x) = (5 - 7)^2
