You can put this solution on YOUR website! y = 2(x + 8)^2 + 10
This is an equation of a parabola that opens upwards
Standard form: A(x-h)^2+k, (h,k)=(x,y) coordinates of vertex, A=coefficient
For given equation: y=2(x+8)^2+10
vertex:(-8,10)
A=2
y-intercept:set x=0
y= 2(x + 8)^2 + 10
= 2(0+8)^2+10
=2*64+10=138
