Find the area of a regular pentagon with side equal to 3 and apothem equal to k

If h(x) = f[tex]h(x) = f[/tex] ° [tex]g) (x)[/tex] and [tex]h(x) = \sqrt[3]{x+3}[/tex], find [tex]g(x)[/tex] if [tex]f(x) = \sqrt[3]{x +2}[/tex] ·

How many zeros does the function f(x)=4x3-x2+1 have

Any is very appreciated! (picture is provided below)not sure how to do this at all won't lie
