Write a rational function with no vertical asymptotes and no holes. Please explain.

Ksju [112]

ANSWER

$f(x) = \frac{ {x}^{2} }{ {x}^{2} + 1 }$

EXPLANATION

We write the function such that both the numerator and the denominator are prime.

An example of a rational function with no vertical asymptotes and no holes is

$f(x) = \frac{ {x}^{2} }{ {x}^{2} + 1 }$

For the above rational function, the denominator is never zero, so there are no vertical asymptotes.

Also the highest common factor for the numerator and the denominator is 1 so there are no holes.

How many solutions does the equation 6z - 3z - 7 = -2 + 3 have?

erik [133]

Answer:

One

Step-by-step explanation:

6z - 3z - 7 = -2 + 3

Combine like terms

3z-7 = 1

Add 7 to each side

3z-7+7 = 1+7

3z=8

Divide each side by 3

3z/3 = 8/3

z = 8/3

There is one solution
