Produce graphs of f that reveal all the important aspects of the curve. Then use calculus to find the following. (Enter your answers using interval notation. Round your answers to two decimal places.)

f(x) = x5 − 5x4 − x3 + 28x2 − 2x

a) Find the interval(s) of increase/decrease.

b) Find the inflection points of the function.

c) Find the interval(s) where the function is concave up.

d) Find the interval(s) where the function is concave down.

Hi, thank you so much for potentially answering my question! I've been having a lot of problems with these questions!
