Question

Evaluate the function g(x) = –2x2 + 3x – 5 for the input values –2, 0, and 3.

Answer 1

Answer:

input =  –2, g(-2) = -19

input =  0, g(0)  -5

input =  3, g(3) =  -14

Answer 2

g(x) = –2x2 + 3x – 5

input =  –2, g(-2) = –2(-2)^2 + 3(-2) – 5 = -8 - 6 - 5 = -19

input =  0, g(0) = –2(0)^2 + 3(0) – 5 = -5

input =  3, g(3) = –2(3)^2 + 3(3) – 5 = -18 + 9  - 5 = -14
