It's a calculus quiz. Can you help me answer it please?

1, The graph of a terics differentiable function f is shown in the figure at right, Which is true? Explain your reasoning d) f" (1) = [ () = [() 8 ) 1" (1 ) > [' (1) > / () 2, Let f be the function given by ( ( ) = 22 4 2x -12x, ") Find the intervals on which f() is increasing, Show the analysis that leads to your conclusion, b) Find the * coordinates of anly readys extrema, Label them as min or mak, 3 , Let foe the function given by 101) = 25 42 -21% #) Find intervals on which f is concave up, Show the analysis that leads to your conclusion
