What is the y -intercept of the quadratic function f of x is equal to open paren x minus 6 close paren times open paren x minus 2 close paren ?

The y-intercept occurs where x = 0. Substituting into f(x) = (x − 6)(x − 2) gives f(0) = (−6)(−2) = 12, so the y-intercept is the point (0, 12), choice C.
