For each set of points given below, write a possible equation for a quadratic function in standard form. Homework Help ✎
(–3, 0) and,
(–3, 0), (2, 0), and (3, –12)
These are the x-intercepts, so work backwards by using the Zero Product Property to write an equation in factored form.
y = 2x2 + 5x – 3
See part (a).
Now substitute in the coordinates of the point (3, −12) to solve for a.
