PLEASE HELP WILL MARK BRAINIEST Create a rational expression that satisfies the following criteria:
1) Domain is all reals except 1 and -1
2) x=1 is a vertical asymptote
3) X = -1 is a hole
4) There is a horizontal asymptote at y = 3

y = (3x² + x - 2)/(x² - 1)

Step-by-step explanation:

(x - 1)(x + 1) = x² - 1

In the denominator

f(x)/(x² - 1)

f(x) has a factor (x + 1)

3 + (x + 1)/(x² - 1)

(3x² - 3 + x + 1)/(x² - 1)

y = (3x² + x - 2)/(x² - 1)

Step-by-step explanation:

Vertical asymptotes are places where the denominator of a rational expression equals 0 because in those scenarios, we have something like k/0, where k is any expression. This is undefined.

Since x = 1 is a vertical asymptote, we need to make sure we put (x - 1) in the denominator because when we set that equal to 0, we get x = 1.

The domain says that it's all reals except 1 and -1. Domain is all the possible x values. We already covered 1 because we put (x - 1) in the denominator. Similarly, to make sure that the domain doesn't include -1, we need to put x + 1 in the denominator.

Now, we see that x = -1 is a hole. A hole is a removable point of discontinuity. This means that (x + 1) needs to be in the denominator and numerator. That way, we can "remove" it by cancelling it out from the top and bottom, but it still counts as a vertical asymptote.

Finally, there is a horizontal asymptote at y = 3. We get horizontal asymptotes when y approaches a value. A property of horizontal asymptotes is that when the degree of the numerator and denominator of a rational expression are equal, the horizontal asymptote is just the ratio of their leading coefficients. That's why I made sure that both the top and bottom had degrees of 2 by adding an x to the numerator, and I also added a 3 to the numerator so that the leading coefficient of the numerator is 3 and leading coefficient of the denominator is 1, making the ratio 3:1 = 3.

Hope this helps!

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
