Can someone help me with my assignment? The question is, Give three different quadratic functions that have the same zero/s. Show that they have the same zero/s. Draw their graphs in one Cartesian Plane.(Don't graph it anymore, I'll be the one to graph it myself)

Answer 1

y = a(x-p)(x-q)

using three different values of a will produce three different polynomials.

Graphing them will produce parabolas that all cross the x-axis at the same two places (if at all), but are scaled differently.
