Part A.
In this part we have to find the increasing interval .
Increasing interval is that interval where graph goes up. And from the graph we can say that the graph goes up in the interval

And that's the increasing interval .
Part B.
Correct option is B
x and y intercepts
x intercept is the point where graph touches the x axis. And the graph touches the x axis at x=-1 and 1 .
So the x intercepts are

y intercepts are the point, where the graph touches or crosses the y axis.
Therefore the y intercept is (0,1)
So the correct option is D .
The answer is 7x+7/x^2+3x-10

The circumference of the pool is 26.38 meters
<h3>How to determine the circumference?</h3>
The radius, r is given as:
r = 4.2
The circumference, C is calculated using:

This gives
C =2 * 3.14 * 4.2
Evaluate
C = 26.38
Hence, the circumference of the pool is 26.38 meters
