Question

question #1
the graph of a polynomial function is shown below. determine the negative interval(s) for the function.
(-1,1)∪(3,∞)
(-1,3)
(-∞,-1)∪(1,3)
(-3,3)

Explanation:

Step1: Identify x - values for negative y - values

The function is negative when the graph is below the x - axis.

Step2: Determine the intervals

By observing the graph, the function is below the x - axis for \(x\in(-\infty,- 1)\cup(1,3)\).

Answer:

\((-\infty,-1)\cup(1,3)\)
