### Graph Description
The graph depicts a function \( y = f(x) \) with the x-axis ranging approximately from \(-15\) to \(15\) and the y-axis from \(-10\) to \(15\). Key points of observation are:
- The graph is decreasing from \( x \approx -15 \) to \( x = -10 \).
- It increases from \( x = -10 \) to \( x = -5 \).
- It decreases again from \( x = -5 \) to \( x = 5 \).
- It increases from \( x = 5 \) to \( x = 10 \).
- It has another increase from \( x = 10 \) to beyond \( x = 15 \).
### Question a
On what open interval(s), if any, is the function increasing? Select the correct choice below and fill in any answer boxes within your choice.
- **A.** [Input box for interval]
(Type your answer in interval notation. Use integers or fractions for any numbers in the expression. Use a comma to separate answers as needed.)
- **B.** The function is never increasing.
### Instructions
- Review the graph to identify intervals where the function is increasing.
- Enter the intervals in interval notation within the provided answer box if option A is chosen.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F93ade889-6aa6-440d-b6d3-23ce5a98ca6e%2F165ae221-ea03-457e-8d2d-f8740753f665%2F7j22y3b_processed.png&w=3840&q=75)
