Quadratic function f(x) = 2x² - 8x +9 can be expressed in the form f(x) = a(x-p)? +q where a, p, and q are constants. State the values of a, p and q. -

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
