Find any points of discontinuity for each rational function. Sketch a graph. Describe any verticals or horizontal asympyoyes and
AVprozaik [17]
For
  y = (x^2 -4)/((x +2)(x^2 -49))
the numerator factors to (x -2)(x +2), so the factor of (x +2) will cancel with that in the denominator, leaving
  y = (x -2)/(x^2 -49)

There are points of discontinuity at the hole, x=-2, and at each of the vertical asymptotes, at x=-7, +7.
The horizontal asymptote is y=0.

Use the linear equation to answer the question <br> y=2/3x-3 <br> y=-3/2x+2
Colt1911 [192]

Answer:

Step-by-step explanation:

3y = 2x - 9

2y = -3x + 4

3x + 2y = 4

-2x  + 3y = -9

6x + 6y = 8

-6x + 9y = -27

15y = -15

y = -1

3(-1) = 2x - 9

-3 = 2x - 9

6 = 2x

3 = x
