Exam points

  • Sketch modulus cubic graphs by reflecting negative parts above the x-axis.
  • Mark intercepts of cubic or modulus graphs when drawing the sketch on axes.
  • Use horizontal-line intersections to decide values of k with a stated number of solutions.

4.4. Sketch cubic polynomials and moduli question 1

[Maximum number: 3]

On the axes, sketch the graph of y=−15(x+2)(2x−1)(x+5)y=-\frac{1}{5}(x+2)(2 x-1)(x+5), stating the intercepts with the axes.
