Functions Defined By Equations: solve f(x) = 0 for f(x) = x^

[sk8rgirl130]

For each function, (a) find f(0), and (b) solve f(x) = 0
f(x) = x^2 - 13x + 40



I completed (a) and got f(x) = 40.

I need help figuring out (b)

Plug "0" in for "f(x)" to get:

. . . . .0 = x² - 13x + 40

Then solve the quadratic equation by whatever method you prefer. You could solve by factoring, since x² - 13x + 40 = (x - 5)(x - 8), or you could always use the Quadratic Formula.
