Question

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

Answer 1

Answer:

(g o h)(5) = 4

Step-by-step explanation:

h(x) = x - 7

g(x) = x^2

(g o h)(5) = ?

(g o h)(x) = g(h(x)) = (x - 7)^2

(g o h)(5) = (5 - 7)^2 = (-2)^2 = 4

Answer 2

Answer:

g°h(5)=4

Step-by-step explanation:

g°h(5)=g( h(5))

h(5)=5-7=-2

g(-2)=(-2)^2=2^2=4
