Question

PLZ HELP!! Select the correct answer.
Which rational equation fits the graph?

Answer 1

C

Explanation:

When we set the numerator equal to 0 and solve for x, that value is the horizontal asymptote (a line the graph come towards, but never crosses).

Looking at the graph, the horizontal asymptote is x = 2, so which one of the 4 functions has a horizontal asymptote of 2? Let's check.

A) 2x - 1 = 0

x = 1/2

B) same, x = 1/2

C) 2x -4 = 0

x = 2

D) same as A,B, x = 1/2

As we can see, option C has the right horizontal asymptote and A,B,D are eliminated. So answer is C.
