Question

I didn't understand this one.

Let g(x) = 2x2 - 11x. Find g(-1).

Answer 1

g (x) = 2x2 - 11x
g (-1 ) = 2 ( -1) ^2 - 11 ( -1)
you just need to replace the x by -1 and obtain the answer...

Answer 2

just like y = 2x2 -11x
and its telling you when x = -1 find y
what you normally do is replace -1 in the equation y = 2x2 -11 x
= 2 (-1) ^2 -11 (-11) :D

Answer 3

I still don't understand. :C I'll post the answer choices.

Answer 4

hep check your calculations ... g ( -1 ) = 2 (-1)^2 - 11 (-1) = 13

Answer 5

2(-1)^2 = 2 and -11 (-1 ) = 11
2+11 = 13... just try again with your calculation the ans is D

Answer 6

Okay.
