Question

Which of the following rational functions is graphed below?​

Answer 1

The graph represents the function (D) because the graph of the function  is not defined at x = 1 and x = 2 option (D) is correct.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a graph of a function:

If we take the function:

$\rm f(x) = \dfrac{1}{\left(x-1\right)\left(x-2\right)}$

At x = 1 and x = 2 the function will be not defined, so this region would be hollow and as we can see in the graph of a function.

The function is not defined at x = 1 and x = 2.

Thus, the graph represents the function (D) because the graph of the function is not defined at x = 1 and x = 2.
