Determine the equation of any vertical asymptote and the value of x for any hole in the graph of the rational function fx x-2 over xsquared-x-2?
Asymptote's occur when your equation has a denominator of zero Holes may occur when your equation has both a numerator and denominator of zero So... The equation for the denominator equals zero is:
x2-x-2 = 0 The equation for both the numerator and denominator equals zero is
x - 2 = x2-x-2 = 0 For interests sake... lets solve it.
---- x2-x-2 = 0
(x+1)(x-2) = 0
x = -1, 2 x - 2 = x2-x-2 = 0
x - 2 = 0
x = 2 A vertical asymptote occurs at x = -1
A vertical asymptote or hole may appear at x = 2
What else can I help you with?
How do I determine the domain and the equation of the vertical asymptote with the equation f of x equals In parentheses x plus 2 end of parentheses minus 1?
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.
What are the asymptotes of a linear function?
Considering an asymptote as a tangent to the curve "at infinity", the asymptote is the straight line itself.
Does every rational function has at least one horizontal asymptote?
Nope not all the rational functions have a horizontal asymptote
If a function has a vertical asymptote at a certain x-value then the function is at that value?
Undefined
How do you determine if a relation represents a function?
If the function is a straight line equation that passes through the graph once, then that's a function, anything on a graph is a relation!

Does every rational function have an asymptote?
No if the denominators cancel each other out there is no asymptote
True or False if a rational function Rx has exactly one vertical asymptote then the function 3Rx should have the exact same asymptote?
It will have the same asymptote. One can derive a vertical asymptote from the denominator of a function. There is an asymptote at a value of x where the denominator equals 0. Therefore the 3 would go in the numerator when distributed and would have no effect as to where the vertical asymptote lies. So that would be true.
Does every rational function have more than one vertical asymp tote?
No.The equation x/(x^2 + 1) does not have a vertical asymptote.

The horizontal asymptote for exponential function is?
The graph of an exponential function f(x) = bx approaches, but does not cross the x-axis. The x-axis is a horizontal asymptote.
Does every rational function has at least one horizontal asymptote?
Nope not all the rational functions have a horizontal asymptote
An asymptote is a line that the graph of a function?
approaches but does not cross
Should you check the value of a function on its asymptote to get a good idea of how its graph should look?
The asymptote is a line where the function is not valid - i.e the function does not cross this line, in fact it does not even reach this line, so you cannot check the value of the function on it's asymptote.However, to get an idea of the function you should look at it's behavior as it approaches each side of the asymptote.
