Award is medal, my last question for the night :)

Answer 1

everywhere you see an x, replace it with 1/2

Answer 2

then evaluate/simplify

Answer 3

p(x) = -13x^3 + 5x^2 - 3x + 2

p(1/2) = -13(1/2)^3 + 5(1/2)^2 - 3(1/2) + 2

p(1/2) = ???

Answer 4

So. -13(1/2)^3?

Answer 5

don't forget the parenthesis

Answer 6

that's part of it

Answer 7

yeah, x is the input so you replace 1/2 anywhere you see an x

Answer 8

and then solve

Answer 9

-13(1/2)^3+5(1/2)^2-3(1/2)+2
