For the function y = 3x2 - 12x + 4, what’s the mirror point for the y-intercept? Remember to type your point in the form (x,y) without any spaces.

Answer:

  (4,4)

Step-by-step explanation:

The axis of symmetry is ...

  x = -b/(2a) = -(-12)/(2(3)) = 2

So, the x-coordinate of the point symmetric with the y-intercept is 2·2 = 4. The y-intercept is 4, so the "mirror point" is (4, 4).
