Need help with these problems, but only using Calc 1 methods (no integrals). Thank you.

(2) (2-6) Determine the intervals on which the function is increasing and intervals on which the function is decreasing. Check your answers by graphing the corresponding functions. Include hand sketched or screenshot copies of these graphs. f(1) = (x - 1)3 - 2. (3) f(x) = sin x + 2 restricted to I E (-2, 2). (4) f(x) = cos r + 2 restricted to I E (-2, 2). (5) f(1) = EV1 - I restricted to I
