  1. Quadrant 1 graph increasing straight line.

    Graph (a) is linear. Straight lines grow at a constant rate. Which function on the table is growing at a constant rate.

  2. Increasing concave down graph

    Graph (b) is increasing (the y-values are going up), but it is getting less and less steep as it increases. Which function is getting less and less steep?

    Steepness can be determined by rate of change: 

  3. Graph increasing concave up

    Graph (c) is increasing (the -values are going up), AND it is getting more and more steep as it increases.

Use the eTool below to create the graphs of the functions.
