Warm Up

Here is a graph of a function ww defined by w(x)=(x+1.6)(x2)w(x)=(x+1.6)(x2). Three points on the graph are labeled.

A parabola on a coordinate grid that does not have a scale or numeric values. The upward facing parabola intersects the x-axis at two points (a, b) and (c, d) and it intersects the y-axis at the point (e, f). The point (a, b) is on the left side of the parabola while the point (c, d) is on the right side of the parabola.

Use the graph to answer the following questions.

1.

Find the value of aa. Be prepared to explain your reasoning.

2.

Find the value of bb. Be prepared to explain your reasoning.

3.

Find the value of cc. Be prepared to explain your reasoning.

4.

Find the value of dd. Be prepared to explain your reasoning.

5.

Find the value of ee. Be prepared to explain your reasoning.
