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

Answer:  4

=====================================================

Displayed Work:

Now substitute x = 5

---------------------

Alternative approach:

h(x) = x-7

h(5) = 5-7

h(5) = -2

Thus

g(h(5)) = g(-2)

and

g(x) = x^2

g(-2) = (-2)^2

g(-2) = 4

Thus giving

Answer:

(5 – 7)²

Step-by-step explanation:

(5 – 7)² equals 4
