How do I graph this function? f(x)=2|x|+1
The same as all graphs.
Pick values for x, find f(x), plot the points, draw straight lines thru them.

How do I find the Maximum value of this function? f(x) = -2x^2 + 2x - 3
It's the vertex, on the Axis of Symmetry (AOS)
The AOS is x = -b/2a = -2/-4 = 1/2
Max = f(1/2)
