f(x)= (x-7) /(-2x+7)(2x+5)
set -2x+7=0
-2x=-7
x=7/2
set 2x+5=0
2x=-5
x=-5/2
x=7/2 and x=-5/2 are vertical asymptotes.
a negative divided or multiplied by a negative is a positive a negative and a positive multiplied or divided by each other is a negative a negative divided or multiplied by a negative is a positive a negative and a positive multiplied or divided by each other is a negative

Solve? 2 is where the right piece of this function crosses the X axis, but the vertical asymptote is important here.(X - 3)/(X + 2)divide both terms, top and bottom by X- 3/X divided by 2/Xsame as- 3/X * X/2= - 3/2========the vertical asymptote
a negative divided or multiplied by a negative is a positive a negative and a positive multiplied or divided by each other is a negative a negative divided or multiplied by a negative is a positive a negative and a positive multiplied or divided by each other is a negative
y = 1. When the degree of your numerator is the same with the degree of your denominator, then y = the ratio of the leading coefficients of the numerator and denominator is the horizontal asymptote.
negative 9 divided by negative 3 is 3 andnegative 3 minus 1 is negative 2
The domain of the function f(x) = (x + 2)^-1 is whatever you choose it to be, except that the point x = -2 must be excluded. If the domain comes up to, or straddles the point x = -2 then that is the equation of the vertical asymptote. However, if you choose to define the domain as x > 0 (in R), then there is no vertical asymptote.

minus (negative) A negative number multiplied or divided by a negative is a positive. Then, multiplied or divided by another negative gives you a negative. A negative added to a negative is a negative. So adding a third negative is still a negative. Subtracting a - from a - is a -. So, subtracting a third - is still a -. No matter what operation you do, three negatives is a negative.
negative 3
A negative number divided by a positive number, or a positive number divided by a negative number, results in a negative number.
No, 12/-4 = -3 A negative times negative is positive, so positive divided by negative is a negative.
