Analyzing Families of Functions with Calculus in MATLAB

Analyzing the "witch" function

>>witch(x,param)= 8*param/(4 * PI *(4*param^2+(xval-pi)^2))

Using the 'witch' function analyze the following characteristics: using c=1, 2, and 3/4 as examples.

Equations

Graphs

Intercepts

Asymptotes

Intervals of Increasing and Decreasing & Local Extrema

Intervals of Concavity & Inflection Points

Role of the Parameter

Example using a different function and further description of the lab

I am having trouble determining the code for what they are asking for, any help would be greatly appreciated
