please help me with these questions and show all work/explanations so I can understand, thank you so much.

A graphing calculator is recommended. Use the Squeeze Theorem to show that lim xcos(6xx) = 0. x - 0 Illustrate by graphing the functions f(x) = -x2, g(x) = x2 cos(6xx), and h(x) = x2 on the same screen. Let f(x) = -x2, g(x) = x2 cos(6xx), and h(x) = x2. Then ? @ s cos(6xx) S ? @ = ? @ sx cos(6xx) S ? @ . Since lim f(x) = lim h(x) = x - 0 , by the Squeeze x - 0 Theorem we have lim g(x) = x - 0 -Use the given graph of f to find a number o such that if 0
