A ball is thrown, and its height is recorded a number of different times. The ball reaches a maximum height of 20 m after 1.5 s.

How do you sketch this relation from just a vertex.
Grade 11 functions

1 answer

You know the vertex is at (1.5,20)
You know it passes through (0,0)
Use symmetry to draw the other half of the parabola. It also passes through (3,0)
