Question

question #4 the graph of a polynomial function is shown below. determine the positive interval(s) for the function. (-3,3) (-∞,-1)∪(1,3) (-1,1)∪(3,∞) (-1,3)

Explanation:

Step1: Identify positive - value regions

A function is positive when its graph is above the x - axis.

Step2: Determine intervals

From the graph, the function is above the x - axis when \(x\in(-1,1)\cup(3,\infty)\).

Answer:

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