Question

What is the y-intercept of the quadratic function f(x) = (x – 6)(x – 2)? (0,–6) (0,12) (–8,0) (2,0) Mark this and return Save and Exit

Answer 1

the y intercept is the constant term on the x side

-6 * -2 which is 12

we can foil this out to see that

(x-6) (x-2)

x^2 -6x -2x+12

x^2 -8x+12

so the y intercept is (0,12)
