Answer:
The function would be positive in:
(-9, 3]
Step-by-step explanation:
A function is considered positive on the X-axis when the changed values in the function are greater than zero. f(x) > 0
And is considered negative when f(x) < 0.
In this case, the numbers that make the function positive are the numbers from -9 to 3, but not including -9.
This can be written as (-9, 3]
It means that -9 is not taken but any number greater than -9 is.
