Mary creates a table of values for a function and plots the points. She finds that the difference in the y values is the same. What kind of function did she graph?
How can you tell if a graph is linear, quadratic, exponential or square root?

If the difference in x values is constant and the difference in y values is constant then the slope is constant and we have a straight line.
quadratic is a parabola with one vertex
exponential curves one way
like y = e^x curves up
sqrt slope becomes smaller and smaller
exponential curves one way
