question determine the domain on which the following function is increasing. answer attempt 1 out of 2
Answer
Explanation:
Step1: Recall increasing - function concept
A function is increasing when the graph goes up from left to right.
Step2: Analyze the given graph
Looking at the graph, we see that the function is going up from negative infinity to the x - value of the vertex.
Step3: Identify the x - value of the vertex
The vertex of the parabola (since it is a quadratic - like graph) occurs at the x - value where the function changes from increasing to decreasing. From the graph, we can estimate that the vertex occurs at (x = - 1). So the function is increasing for (x\in(-\infty,-1)).
Answer:
((-\infty,-1))
