Functions of the Form \(y = ax^{3} + bx^{2} + cx + d\)
Functions of the Form \(y = ax^{3} + bx^{2} + cx + d\)
Optional Investigation: The effects of \(a\) on a cubic function
Complete the table below and plot the graphs of \(f(x)\) and \(g(x)\) on the same system of axes.
Be careful to choose a suitable scale for the \(y\)-axis.
\[f(x) = 2x^{3} - 5x^{2} - 14x + 8 \qquad \qquad g(x) = -2x^{3} + 5x^{2} + 14x - 8\]| \(x\) | \(-\text{3}\) | \(-\text{2}\) | \(-\text{1}\) | \(\text{0}\) | \(\text{1}\) | \(\text{2}\) | \(\text{3}\) | \(\text{4}\) | \(\text{5}\) |
| \(f(x)\) | \(-\text{25}\) | ||||||||
| \(g(x)\) | \(\text{25}\) |
