.
Step-by-step explanation:
To obtain x-intercepts, we need to give certain value, specifically
.
However, in case of a rational function, we must make sure that
doesn't makes the denominator null, beacuse in that case the function is undefined.
Therefore, for x-intercepts we must say
for
, with
.
Since the figure is a parallelogram, then SP=RQ, and SR=PQ.
To find SR, we draw right triangle SAR, as shown in the picture, where the coordinates of A are clearly (-3, -2).
Thus, we can see that SA=4 units, and AR=4 units. By the Pythagorean theorem,
Similarly, to find SP, which is equal to QR, we draw the triangle PBS, where the coordinates of B are (-2, 2).
Clearly, PB=3 and SB=1, thus using the Pythagorean theorem in right triangle PBS:

units.
The perimeter of the parallelogram is SP+RQ+SR+PQ=

.
