I need help with questions two and three in the picture. Thank you

Write down the gradient of T. 1g. [2 marks] The graph of fhas a local minimum at point P. Let 7 be the tangent to the graph of fat P. Write down the equation of T. 1h. [4 marks] Sketch the graph of the function f, for -3 s x 5 6 and -7 sys 15. Indicate clearly the point P and any intercepts of the curve with the axes. 1i. [2 marks] On your graph draw and label the tangent T. 1j. [1 mark] T intersects the graph of fat a second point. Write down the x-coordinate of this point of intersection. Question Two [Maximum mark 7] 2a. [3 marks] Let f (x) = xcosx , for 0 S x $ 6. Find f'(x) . -1 0 2b. (4 marks] -1 On the grid shown, sketch the graph of y = f' (x) . -2 -3 Question Three [Maximum mark 7] 3a. [4 marks] Let g(x) = Inx 2. for x > 0. Use the quotient rule to show that g'(x) = 1-2inx x3 3b. [3 marks] The graph of g has a maximum point at A. Find the x-coordinate of A
