I need help on question 6 and the graph part too. pls show clear writing 

Question 6 0/1 pt 399 Details Given the function f(x) = - 3x² f(a+h)-f(x) Find the difference quotient - h f(x+h)-f(x) Find f'(z) by determining lim h?0 h Find f'(-2) (This slope should match the tangent line you drew above.) Find f'(0) Find f'(1) Graph the function f(x) = - 3z² and draw the tangent lines to the graph at points whose x-coordinates are -2, 0, and 1. Clear All Draw: -/^
