Graph the function f(x) = - 2x and draw the tangent lines to the graph at points whose x-coordinates are -2 , 0, and 1. -10 Clear All Draw: Find the difference quotient f (x th) - f(z) h Find f' (x) by determining lim f ( I t h) - f(I) h -+ 0 h Find f'( - 2) (This slope should match the tangent line you drew above.) Find f' (0) Find f' (1)
