You can put this solution on YOUR website!
y=x^2+2x-6
generate variuos values of y for +ve & -ve values of x.
find the vertex x= (-b/2a)=-1
y= -7
..
graph%28500%2C500%2C-10%2C10%2C-10%2C10%2Cy=%28x%5E2%2B2x-6%29%29
x intercept = 1.6,-3.6
y intercept = -6
vertex (-1-7)
..
these values can be confirmed by calculations.
