Answer:
Function (4 < x < 6) and (8 < x < 10) is decreasing
Function (1 < x < 4) and (6 < x < 8) is increasing
Function (10 < x < 14) is neither increasing nor decreasing
Step-by-step explanation:
The question is incomplete. The complete question has been added as an attachment.
From the graph:
x-axis (horizontal), y-axis (vertical)
Note: moving from negative bigger number to negative smaller number is an increase.
Moving from negative smaller number to negative bigger number is a decrease.
6 < x < 8: on the x-axis, from number +6 to +8, you find on the y-axis the line moved from -7 to -4. That is an increase.
4 < x < 6: on the x-axis, from number +4 to +6, you find on the y-axis the line moved from -3 to -7. That is a decrease.
10 < x < 14: on the x-axis, from number +10 to +14, you find on the y-axis the line moved from -5 to -5. It remained on the same number. It is neither increasing nor decreasing.
8 < x < 10: on the x-axis, from number +8 to +10, you find on the y-axis the line moved from -4 to -5. That is a decrease
1 < x < 4: on the x-axis, from number +1 to +4, you find on the y-axis the line moved from -11 to -3. That is an increase.
