FNGR 2 | Lesson 1 | Explore (Function Matching)

See how well you understand function expressions by trying to match your function graph to a generated graph. Choose from several function types or select random and let the computer choose.  This activity is on NCTM platform.

Function Matching: Instructions

Function Matching: Activity

After exploring and matching the expressions to the graphs, move on to the next exploration about the coefficients and the constants of quadratic functions.  Pay close attention to what $$a$$, $$b$$ and $$c$$ do and what effect they have on a parabola.  Don’t be shy, even try the wild side with negative coefficients and constant.

What did you determine about $$a$$, $$b$$ and $$c$$ and how they effect a parabola?  Let’s see if you are on the right track.
