Answer:
-8 ≤ x ≤ - 6
2 ≤ x ≤ 6
Step-by-step explanation:
Increasing part of the function can be easily determined from the graph.
Note that increasing function means for each successive values of 'x', the values of 'y' keep increasing.
From the graph, we see that the function is increasing in the interval
Between -6 and -4, the graph is constant and takes the value 4.
After that it decreases till x = -2 until it becomes a constant function again on x = 2.
Then, it again increases from x = 2 till x = 6. This is represented by the interval
.
Then it again decreases.
So, OPTION A and C are the answers.
They way to find the y-intercept from two points is to first find the slope, which can be derived from the formula .
Then, you can plug in one of the two points or
into the formula y=mx+b to solve for b, which is your y-intercept.
