Unit 11: Coordinate Geometry II – Graphing quadratic and linear functions

This online tool lets you "play" with different values for a, b and c in a standard form quadratic equation. Have Fun! []

I found this link helpful. It helped me to understand the topic to a better extent. Thanks!

The ever-famous purple math link is back! This site always has helpful information. :) I hope this helps you, too!

For the quickest way to solve these problems is by finding the axis of symmetry. -b/2(a). WOOP! If you have a data chart with a quadratic equation as the function the plots on the should make a parabola (it looks like a smiley face or a sad face ). Then if you plug the list and the quadratic equation into the calculator the plots and line from the equation should match up. If they don't then you made a mistake somewhere.

I like to find the axis of symmetry first when graphing quadratic equations. I think by using the formula -b/2a to find the axis of symmetry it is easier than to graph the parabola.

[] This website has a lot of helpful info. I hope it helps!

I also like to find the axis of symmetry first, but then I plug in the axis of symmetry into the data table for that graph. I believe this system works better than just finding different plots.

I also like to find the axis of symmetry first (-b/2a). After I find the axis of symmetry's x value I plug it into the data table. All the x-values are inputs and all the y-values are the outputs. Then you find some similar values and then plot them all on the graph. The x-value in the axis of symmetry will be the highest or lowest point of the parabola.

[] When graphing 2 equations at once there are certain steps that you should follow. 1. Graph and label each line. 2. Find points of intersection. 3. Finally check your solution.

The formula for finding exponential growth is P(1+r)^T. The formula for exponential decay is P(1-r)^T.
