Answer 1

What is the meaning of the points (2,−50), (3,0), and (4,150)?

Answer 2

the point 2,-50 is the vertex of the parabola
at x=2 the minimum value of the curve is -50
the curve crosses the x-axis when x=3
or 3 is one of the zeroes of the polynomial represented by the curve
when x =4 the value of the polynomial is 150

Answer 3

Explain how you know what type of function could be used to model this situation.

Answer 4

It looks like a parabola y = (x-a)^2 with min at a

suspect this because of the u shape of the curve

Answer 5

Use the x-intercepts of the graph to find an equation for the function whose graph is shown. (Use your graphing calculator to check and adjust your model, if needed.)
