Carsen Simon · Answer 1

(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

Ashley Thomas · Answer 2

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
