    1. The problem statement, all variables and given/known data

    I have no idea on how to approach this question, Any help is appreciated immensly.

    Draw a sketch of a function with the following properties:

    a) The gradient is negative where -2 < x < 2
    b) The gradient is positive where x < -2 and where x > 2
    c) The gradient of the function is zero at (-2, 1) and (2, -1)
    d) The zeros of the function are (-4, 0); (0, 0); and (4, 0)
