11-69.

Based on the graph, give a possible equation for the parabola.

*11-69 HW eTool*(Desmos). Homework Help ✎

For additional help, see problem 11-13.

The *x*-coordinates of the *x*-intercepts are roots of the equation. If you know the roots, can you find the factors?

The factors are (*x* − 0) and (*x* − 4).

*y* = *x*(*x* − 4)

See the hints in part (a).

Instead of using fractions, multiply each factor by the fraction's denominator.

The factors can be written as

(2*x* + 1) and (2*x* − 3).
