f(x) = 6x2 / (x2+9)
Instruction: If you area asked to find a function enter a function if you are asked to find x- or y-values enter either a number a list of numbers separated by commons, or None if there aren't any solutions Use interval notation if you are added to find an interval or union of intervals and enter if the interval is empty
a. Calculate the first derivative of f Find the critical numbers of f. where it is increasing and decreasing and its local extrema.
b. Calculate the second derivative of f find where f is concave up concave down and has inflection points.
c. Find any horizontal and vertical asymptotes of f.
