Need with rational function question for precalculus

Answers: 1), 2), 3).

Step-by-step explanation:

Note that when we say , we mean "as x tends to a from the left hand side". That is, what is the function doing when "x approaches a from the left side". In much the same way, we say to imply what the function is doing when "x approaches from the right side".

So, when , we are looking at the point around x = 3, but from the left side. From the graph, we see that, from the left side of 3, the graph is approaching a fairly big number. So, we see that: "As , ".

In much the same way:

"As , ".

"As , ".

you can't solve x because it is 2 linear equation and you only have one equation
