Question

If f(x)= 2x+5 and g(x)= 3x2 +2x+5, what is f(3)+g(2)?

Answer 1

Answer:

32

Step-by-step explanation:

1. find f(3) = 2x + 5

a) y = 2(3) + 5

b) y = 6 + 5

c) y = 11

2. find g(2) = 3x² + 2x + 5

a) y = 3(2)² + 2(2) + 5

b) y = 3(4) + 4 + 5

c) y = 12 + 4 + 5

d) y = 21

3. add f(3) + g(2)

a) 11 + 21

b) = 32
