identifying increasing and decreasing intervals\nwhich statement is true regarding the intervals where the function is increasing and decreasing?\nthe function is increasing from (-∞, 0)\nthe function is increasing from (0, ∞)\nthe function is decreasing from (-∞, 0)\nthe function is decreasing from (-∞, ∞)
Answer
Explanation:
Step1: Recall function - increasing and decreasing definitions
A function (y = f(x)) is increasing on an interval if for any two points (x_1) and (x_2) in the interval with (x_1<x_2), (f(x_1)<f(x_2)). It is decreasing if (f(x_1)>f(x_2)) for (x_1 < x_2).
Step2: Analyze the given graph
Looking at the graph of the function, as we move from left - hand side ((x=-\infty)) to (x = 0), the (y) - values of the function are getting larger. As we move from (x = 0) to (x=\infty), the (y) - values of the function are getting smaller.
Answer:
The function is increasing from ((-\infty,0))
