The graph of a function is shown.

Drag the interval with the appropriate description:

Decreasing: ​ (a)  

Increasing: ​ (b)  

Positive: ​ (c)  

Negative: ​ (d)  

• [-2, 0)
• (0, 4]
• (-4, -1)
• (0, 2]

• The margin of error for the mean grade point average is about 0.057.

• The margin of error for the mean grade point average is about 0.092.

• The margin of error would decrease if the sample size were changed to 125 seniors.

• The margin of error would increase if the sample size were changed to 125 seniors.

Which function does not have the set of all real numbers as its domain?

• 4 units

• 7 units

• 14 units

• 17 units
