what is the interval of increase? all real numbers (0,2) (-3, ∞) (1, ∞)
Answer
Answer:
C. ((-3, \infty))
Explanation:
Step1: Understand the concept of interval of increase
A function is increasing on an interval if, for any two points (x_1) and (x_2) in the interval with (x_1<x_2), we have (f(x_1)<f(x_2)).
Step2: Analyze the graph
Looking at the graph, we observe that for (x > - 3), as (x) increases, the (y -) value of the function also increases. For (x\leq - 3), the function is not increasing. So the interval where the function is increasing is ((-3,\infty))
