Use the parabola tool to graph the quadratic function.

f(x)=2x^2+4x−16

Graph the parabola by first plotting its vertex and then plotting a second point on the parabola.

An observer(o) spots a plane(p) taking off from a local airport and flying at a 29 degree angle horizontal to her line of sight and located directly above a tower(t). the observer also notices a bird circling directly above her. if the distance from the plane(p) to the tower(t) is 6,000ft., how far is the bird(b) from the plane(p).
