Which of the following rational functions is graphed below?

A.

Step-by-step explanation:

A rational-polynomic function is a function of the form:

(1)

There are three important remarks on this kind of function:

1)   when function passes through the x-axis.

2) If , then the function has a vertical asymptote.

3) The horizontal asymptote is a linear function of the form .

In accordance with the graph, the function has two vertical asymptotes at and , numerator becomes zero for and horizontal asymptote is as grade of numerator is less than grade of denominator.

Hence, we conclude that rational function is . (Correct A)

tube or goog would be a great resource to with that question

exa:

3+11

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
