Left side goes to negative infinity, as x approaches negative infinity
right side goes to positive infinity as x approaches positive infinity
take the derivative to find local max and minimum points, set = 0, solve for x
3x^2 + 4x -13 = 0
lesser solution will be the local max, larger solution will be a local minimum
draw a smooth curve through those points. It goes up, then down, then up forever
Plot a few other points, such as simple values for x, 0, 1, 2, 3, -1, -2, -3
an x intercept is around x=3
