please do the following problems and show the work

93. Suppose we know the derivative of a function f is flies} = 1What is the general shape of the graph of f? The Second Derivative Test Denition 45 For :1 given. function L the second derivative of f is given by re: = re} = g to. If f" [1] estistsJ we say that f is twdcediiierentiable. 99. Suppose you have a twice-differentiable function f. {a} 1What can you say about the graph y = f {1'} when f'IIII} is increasing? How would you describe this shape? {b} 1What can you say about the graph 1; = r} when I' [1) is decreasing? How would you describe this shape? {c} 1When f'{1*} is increasing~ what can you say about f"(5r}? {d} 1When f'{1'} is decreasing, what can you say about Flint}? {e} If e is a critical point for f and if f"(cj :2- l1~ what can you say about the graph y=f[1:} at1'=e? {f} If e is a critical point for f and if f"|:c} :: I], what can you say about the graph yzfx} atsrze? l. How would you describe a method for nding all local rnaz-Lirna and rninirna for a twicediiierentiable function f
