Question

If f(x) = -x + 5 and g(x) = x2, what is (g° f)(-1)?

Answer 1

Answer:

12

Step-by-step explanation:

1. F(x) = - x + 5       G(x) = 2x

2. (g° f) is the same as  G[f(x)]

3. solve f(x) and plug into G(f(x))

4. f(-1) = -(-1) + 5 which eqauls 6

5. plug 6 into g(x)

6. G(6)= 2(6) which eqauls 12
