Graph the function f(x) = - 3x and draw the tangent lines to the graph at points whose x-coordinates are -2 , 0, and 1. Clear All Draw: Find the difference quotient f(x + h) - f(z) h Find f' (x) by determining lim f ( Ith) - f(x) h -+ 0 h Find f' ( - 2) (This slope should match the tangent line you drew above.) Find f' (0) Find f' (1)
