You can put this solution on YOUR website!
Sketch the graph of the function. Label the vertex."
My question is:
y = x^2+4x-2
-------------------
Unless you have learned another method the best approach
to graphing this quadratic is to plot points.
If x=0, y=-2
If x=1, y=3
If x=2, y=10
If x=-1, y= -5
If x=-2, y=-6
If x=-3, y=-5
If x=-4, y=-2
If x=-5, y=3
------------------
Plot those points and connect them with a smooth curve.
