Consider the following functions
a. f(x) = 9x^2  x^3
b. f(x) = (x+1)/(x2)
c. f(x) = x^(2/3) * (x5)
For each of the above functions complete the following table. Show the work to justify your answers below the table.
f(x) is increasing on
f(x) is decreasing on
Relative MAX of f(x) is at
Relative MIN of f(x) is at
xintercept of f(x) is at
yintercept of f(x) is at
f(x) is concave up on
f(x) is concave down on
Points of Inflection of f(x) is at

Graph it and you can see. Concavity, max and min, etc.

i have to show my work though
