Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s).Rewrite the following equation in the form y = a(x - h)2 + k. Then, determine the x-coordinate of the minimum.
Accepted Solution
A:
Given: y = 2x^2 - 32x + 56
1) y = 2 [ x^2 - 16x] + 56
2) y = 2 [ (x - 8)^2 - 64 ] + 56
3) y = 2 (x - 8)^2 - 128 + 56
4) y = 2 (x - 8)^2 - 72 <----------- answer
Minimum = vertex = (h,k) = (8, - 72)
=>Β x-ccordinate of the minimum = 8 <-------- answer
