the function is increasing when... (0, ∞) (0, 1.5) (-∞, -1.5) and (1.5, ∞) (-1.5, 1.5)
the function is increasing when... (0, ∞) (0, 1.5) (-∞, -1.5) and (1.5, ∞) (-1.5, 1.5)
Answer
Explanation:
Step1: Recall increasing - function property
A function is increasing when its derivative is positive or when, visually on a graph, the function is rising as we move from left - to - right.
Step2: Analyze the graph
By observing the graph, we can see that the function is rising (going up as we move from left to right) for (x\in(-\infty, - 1.5)) and (x\in(1.5,\infty)).
Answer:
C. ((-\infty, - 1.5)) and ((1.5,\infty))
