Question

Please help!!!

A quadratic relation has an equation of the form y = a(x - r)(x – s).
Determine the value of a when the parabola has x-intercepts at (-2, 0)
and (4,0) and a y-intercept at (0, 16)

Answer 1

he y -intercept is the point at which the parabola crosses the y -axis. The x -intercepts are the points at which the parabola crosses the x -axis. If they exist, the x -intercepts represent the zeros, or roots, of the quadratic function, the values of x at which y=0 . hope it helps
