WebPolynomial Functions (3): Cubic functions. Polynomials of degree 3 are cubic functions. A real cubic function always crosses the x-axis at least once. The derivative of a function at a point can be defined as the instantaneous rate of change or as the slope of the tangent line to the graph of the function at this point. WebA cubic function is of the form y = ax3 + bx2 + cx + d. In the applet below, move the sliders on the right to change the values of a, b, c and d and note the effects it has on the graph. …
