Answer:
Q1 The function is linear from x = 2 to x = 8.
Q2 The function is increasing from x = -5 to x = 0.
Explanation:
Q1. Select the statement that is true about the graph above.
The function is decreasing from x = -5 to x = 0.
This would mean it is going down from left to right. It is obviously going up. So this is not true.
The function is nonlinear from x = -5 to x = 0.
This would mean it is not a straight line, but it is a straight line so this is not true.
The function is increasing from x = 2 to x = 8.
This would mean it is going up from left to right, but it is going down from left to right so this is not true.
The function is linear from x = 2 to x = 8.
This would mean it is a straight line between 2 and 8. It is true.
Q2.Select the statement that is true about the graph above.
The function is increasing from x = -5 to x = 0.
This would mean it is going up from left to right. It is obviously going up. So this is true.
The function is decreasing from x = -5 to x = 0.
This would mean it is going down from left to right. It is obviously going up. So this is not true.
The function is linear from x = 0 to x = 2.
This would mean it is a straight line, but it is not a straight line so this is not true.
The function is nonlinear from x = -5 to x = 0.
This would mean it is not a straight line, but it is a straight line so this is not true.
