To find : Which of the following rational functions is graphed below?
Solution :
A rational function is defined as function in form of p/q where p and q are integers and q is non-zero.
In examining the graph,
It has a vertical assymptote given by x=2.
So, the curve will contain (x-2) in the denominator.
If we see the options we can say that,
The required function is .
Therefore, option C is correct.

Step-by-step explanation:
Given that:
A local trucking company fitted a regression to relate the travel time (days) of its shipments as a function of the distance traveled (miles).
The fitted regression is Time = −7.126 + .0214 Distance
Based on a sample size n = 20
And an Estimated standard error of the slope = 0.0053
the critical value for a right-tailed test to see if the slope is positive, using ∝ = 0.05 can be computed as follows:
Let's determine the degree of freedom df = n - 1
the degree of freedom df = 20 - 2
the degree of freedom df = 18
At the level of significance ∝ = 0.05 and degree of freedom df = 18
For a right tailed test t, the critical value from the t table is :
