Let's do

Release k for some while
If
So
So vertical asymptote is at origin now
It mentioned that it's at x=-5 so we need to change x


- Vertical asymptote at x=-5
Now
- for k=0 horizontal asymptote at origin
But it's given
Same put y=12 in place of k

Graph attached for verification
45 Degrees on each side means it is equal, for an "equilateral" triangle.
All you do is plug in -7 so you get f(x)=8(-7)*15 you get -56*15 which goes to -840
Answer: 18 units squared
Step-by-step explanation:
To find area of a rectangle use A=lw
we can count the units for both and get...
11x2=18
So 18 units squared
