Question

1. what is f(3)? 2. what is f(-2)? 3. find g(10). 4. given g(x) = 17, find x.

Answer 1

Answer:

14, 19, 26, 7

Step-by-step explanation:

f(3) = 2(3)^2 - 3(3) + 5

f(3) = 2(9) - 9 + 5

f(3) = 18-9+5

f(3) = 14

f(-2) = 2(-2)^2 - 3(-2) + 5

f(-2) = 2(4) + 6 + 5

f(-2) = 8 + 6 + 5

f(-2) = 19

g(10) = 3(10) - 4

g(10) = 30-4

g(10) = 26

17 = 3x-4

21 = 3x

7 = x
