I know, you've worked with polynomials before, but we need to make sure that you really understand how their shapes work. I definitely take an artist's approach to these critters!
Understanding shapes and graphs will actually help you to know what some answers in Calculus will be before you crunch them!
I like to call the graphs of polynomials "roller coaster graphs."
![]() | ![]() | ![]() |
Let's review even degree polynomials first. Remember that these | |||
would be polynomials whose leading term is | ![]() | ![]() | ![]() |
etc. |
Starting us off is Standard Parabola Guy. Let's really pay close attention to his basic shape. (I'm just going to draw rough sketches here.)
![]() | The tails both shoot up... We've got one valley. |
This guy touches the x-axis once... It doesn't cross, it just touches (a kiss). | ||
Remember that this is a multiplicity of 2 ( | ) |
