Al changes saved 4. The height of a wave can be represented by the function y = 3 cos ( (2-6)) + 4, with time in z hours. What are the maximum and minimum heights, and when do they occur
on the interval 0 <<24?

Can someone plz me understand how to do these. plz, show work.in exercises 1-4, rewrite the expression in rational exponent form.[tex]\sqrt[4]{625} \sqrt[3]{512} (\sqrt[5]{4} )³ (\sqrt[4]{15} )^{7}\\ (\sqrt[3]{27} )^{2}[/tex]
