200

Write a quadratic equation with a minimum and y-intercept at 2.

What is y=4x²+6x+2

300

Sketch a parabola with a minimum, positive y-intercept, and negative axis of symmetry

What is on the whiteboard (look)?

400

Explain how to find the x-intercepts.

Magic X or quadratic formula

500

Explain how to find the minimum height when a person dives under a lake. 

Find axis of symmetry then plug it in. The y value is the minimum height.
