Question

Use the graph of f(x) to estimate the following.

The x y-coordinate plane is given. The curve enters the window in the second quadrant, goes down and right becoming less steep, crosses the x-axis at x = −10, passes through the approximate point (−8, −11), changes direction at the point (−2, −25), goes up and right becoming more steep, crosses the y-axis at approximately y = −23, crosses the x-axis at x = 6, passes through the approximate point (8, 14), and exits the window in the first quadrant.

(a)

Estimate the vertex.

(x, y) =

(b)

For what x values is the graph increasing? Write the answer using an inequality.

x < −25

x > 2

x < −2

x > −2

x > −25

(c)

For what x values is the graph decreasing? Write the answer using an inequality.
