Question

I have most of A like the x&y int and vertex I just need to know the equation in graphing form.
B I need help with all of it

Answer 1

Step-by-step explanation:

a. $y = 2x^2 + 4x + 2\\y = (2x^2 +4x) +2\\y= 2(x^2+2x) + 2\\y = 2(x^2 +2x +1) + 2 - 2\\y = 2(x+1)^2 + 0\\(h,k) = (-1,0)$

b. $y = -x^2 +2x\\y = -(x^2-2x)\\y = -(x^2-2x+1)+1 \\y = -(x-1)^2+1\\(h,k) = (1,1)$
