Question

PLEASE HELP!!!

If g(x) = 2x4 + 3x3 - x2, find g(-1).
A) -42
B) -12
C) -10
D) -2

Answer 1

-2

Explanation:

g(-1) = 2(-1)4 + 3(-1)3 - (-1)2 = 2(1) + 3(-1) - 1 = 2 - 3 - 1 = -2

Answer 2

The value of g(-1) is -2

Explanation:

`g(x) = 2x^4 + 3x^3 - x^2`

Now we find g(-1)

To find g(-1) plug in -1 for x in the given g(x) equation

Replace all x by -1

`g(x) = 2x^4 + 3x^3 - x^2`

`g(x) = 2(-1)^4 + 3(-1)^3 - (-1)^2`

`g(x) = 2-3-1=-2`

The value of g(-1) is -2
