Question

I know I just fill in -1 with x but I’m stuck with 2 different answers and this is an exam sooooo I don’t wanna risk it. Can someone please tell me the answer?

Answer 1

g(-1) = 4

Explanation:

Given:

g(x) =
`(3x^2 - 2x + 7)/(2x + 5)`

To find g(-1), substitute x = -1

Thus:

g(-1) =
`(3(-1)^2 - 2(-1) + 7)/(2(-1) + 5)`

g(-1) =
`(3 + 2 + 7)/(-2 + 5)`

=
`(3 + 2 + 7)/(-2 + 5)`

=
`(12)/(3)`

g(-1) = 4
