Which statements correctly describe the function shown in the graph? (select the two correct options)

• The function describing the rock's height is decreasing from zero to one second.

• The maximum height of the rock appears to occur 1.5 seconds after being thrown.

• The function is negative for 1.5 < x < 2.5.

• The function is decreasing for 2 < x < 3.

• The function has a maximum value when x = 3.

If the width of a rectangular flower garden is represented by x, and the length is twice the width, with one of the longer sides having a 2-foot-wide walking path, what is the expression for the total area A(x) of the garden including the walking path?

• A(x) = (x)(2x + 2)

• A(x) = (x + 2)(2x)

• A(x) = (x + 2)(2x + 4)

• A(x) = (x + 4)(2x + 2)

Select the correct description of the function that represents the total area of the garden including the walking path.

• A) The function is linear with a domain of all integers.

• B) The function is nonlinear with a domain of all rational numbers greater than 0.

• C) The function is linear with a domain of all rational numbers greater than 0.

• D) The function is nonlinear with a domain of all integers greater than 0.

Based on the graph, what happens to Joe's income from the buffet as the price increase of the buffet goes beyond a certain point?

• It starts to decrease.

• It remains constant.

• It fluctuates periodically.

Joe should increase the cost of the buffet to $______.

• 6

• 8

• 14

• 16

This will increase Joe's his income by approximately $______ each month.

• 1,800

• 4,200

• 8,000

• 9,800

• A graph showing a linear increase in height over time.

• A graph showing a parabolic trajectory peaking at a certain point.

• A graph showing a constant height over time.

• A graph showing an exponential increase in height over time.

• 2

• 3

• 4
