(3) For the function y = x² + 11x – 12. (a) Find the derivative of this function and use this to find the stationary point. (b) Complete the table below, then draw the sign diagram and use it to classify the stationary point of y = x² + 11x - 12. Is it a local maximum or a local minimum? (c) Give all working for finding the x and y-intercepts. (d) Hand sketch the graph. TABLE 2. Table for sign diagram Sign of gradient (positive, negative or 0) x < -5 1/2 X=- -5/2 0 x>- 5/1/1
