9. Mario found the composite function (hºg)(x), where h(x) = 4 -
- ž, and g(x) = 2x + 10.
State which step he made the error and explain the mistake he made in his reasoning,
(2x + 10)
Step 1: h(g(x)) = 4 -
2
Step 2: h(g(x)) = 4 - x + 10
Step 3: h(g(x)) = 14 - X
a. Step 1: 2(4 - Ž)+10
b. Step 2: h(g(x)) = 4 - x + 5
c. Step 2: h(g(x)) = 4 - x-5
d. no error
