Accepted Answer

The graph in $$image_1 ($$piecewise curve with open circles)

Question 2

For the graph in $$image_2$$, on which interval is the function decreasing?

Accepted Answer

$$(0, 3)$$

Question 3

Which graph shows a function that is constant for $$x  0$$?

Accepted Answer

$$image_3$$

Question 4

Accepted Answer

$$image_5$$

Question 5

For the graph in $$image_1$$, what is the domain?

Accepted Answer

$$[-3, 5]$$

Question 6

For the graph in $$image_1$$, what is the range?

$$[-5, 2]$$

Question 7

Which graph represents a function with a maximum value at $$x = 0$$?

Accepted Answer

$$image_2$$

Question 8

For the graph in $$image_3$$, what is the y-intercept?

Accepted Answer

$$y = 1$$

Question 9

Which graph shows a function that is increasing for all $$x$$?

Accepted Answer

$$image_4$$

Question 10

For the graph in $$image_1$$, at which $$x-$$value does the function attain its minimum?

Accepted Answer

$$x = 2$$

Question 11
