Answer:
-5 and +7
Step-by-step explanation:
f(x) = (x²- 3x - 28)/(x² - 2x - 35)
The excluded values of x are those that make the denominator equal to zero.
x² - 2x – 35 =0
(x – 7)(x + 5) =0
x - 7 = 0
x = 7
x+ 5 = 0
x = -5
The excluded values of x are -5 and +7.
The distance is ten because first you minus the -7 to bring you to 0/8 and then you jump over 3 more to give you your distance
For this case we have the following function:

We look for the points of intersection with the x axis, doing y = 0

We look for the points of intersection with the y axis, doing x = 0

We can also observe that the slope is -1.
