Come up with your own twice-differentiable function and draw its graph without a calculator by analyzing its properties. These properties must be included: zeros, symmetry, and first- and second-order derivatives, local and global extreme values, the concavity test, concave up, and concave down. Then, graph your function using your graphing calculators to verify your work.
Here is some additional guidance:
define your function:
don’t make your function too complex or too simple
do not use f(x)=x^2 or something real lame
you are free to incorporate trig functions
factor your function to locate the zeros
describe symmetry with respect to x-axis, y-axis, and origin
Find first derivative and second derivative
Use the first and/or Second Derivative tests to identify local and/or absolute extreme values
Using the second derivatives, describe intervals where the function is concave up and concave down
include a graph of your function
can be hand drawn or done using Desmos
