Answer:
Hi there!
The first one is not a function because it crosses twice using the vertical line test while the second one is a function.
Step-by-step explanation:
The <em><u>correct answer</u></em> is:
90° clockwise
Explanation:
Comparing the image points to the pre-image points, we can see that in every ordered pair, x and y have been switched and x has been negated. Algebraically, this means (x, y)→(y, -x).
This is the same mapping that a 90° clockwise rotation performs, so that is our answer.

We will find the volume of each rectangular prism separately.

<h3>Bottom Figure</h3>



<h3>Adding Together</h3>


It depends on the shape it may be rotation
Part (b)
We use the result of part (a) and plug in (x,y) = (0,0). This is directly from the initial condition y(0) = 0.

-----------------
This means,

is the solution with the initial condition y(0) = 0.
