According to the graph of the rational function

y= 4/x^2-4

which of the following statements is/are true?

I. The function is even

II. The function is increasing for all values in the domain

III. There is a horizontal asymptote along the x-axis,

I only
I and II only
I and Ill only
I, II and III

Answer 1

I and III only

Explanation:

I got it right on the test.

Answer 2

9514 1404 393

Answer:

I and III only

Explanation:

The graph is symmetrical about the y-axis, so is an even function.

The function is decreasing in the 1st quadrant, so is not increasing everywhere.

The values of the function approach y=0 for extreme values of x, so the graph shows that as a horizontal asymptote.

I and III only
