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?

  • Algebra -

    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.

  • Algebra -

    quadratic is a parabola with one vertex

    exponential curves one way
    like y = e^x curves up

    sqrt slope becomes smaller and smaller
