FYI: the answer is not 2

2. The graph of y=2x^2-8x+7 is identical to the graph of y=a(x-h)^2+k for some real numbers a,h,k.

What is the value of k?

 

I SUCK AT PARABOLAS!!! AND MATH IN GENERAL!

1. The parabola is y = -x^2 - 4x + 2, so the answer is (-1)(-4)(2) = 8.

2. Completing the square, we get y = 2(x - 4)^2 - 25, so k = -25.
