determine the domain on which the following graph of f(x) is positive.

determine the domain on which the following graph of f(x) is positive.
Answer
Explanation:
Step1: Identify positive - part of graph
Positive values of (y = f(x)) are above the (x) - axis.
Step2: Determine (x) - intervals
From the graph, the function (y = f(x)) is above the (x) - axis when (x<-5) or (x > - 2).
Answer:
((-\infty,-5)\cup(-2,\infty))
