Question

Evaluate each function at the given value of x.

1. g(x) = -4x^2+ 6 when x = 3



2. f(x) = 6x^4 - x^3 + 3x^2 - 5x + 9 when x = -1



3. g(x) = x^3 - 8x + 6 when x = -3.

Answer 1

Simply substitute
1) x=3 into y= -4x^2 + 6
2) x=-1 into y = 6x^4 -x^3 + 3x^2 - 5x + 9
3) x=-3 into y=x^3 -8x + 6

Answer 2

ok say im doing number 1, I would take the 3 and put it where the (x) is?

Answer 3

yes.

Answer 4

ok, thanks.
