Answer:

We have the following function:


f(x)=-(3)/(x)

The graph of this function has been plotted below. So lets analyze each statement:

1. The function is always increasing.

False

As you can see x increases from -∞ to 0 and decreases from 0 to +∞

2. The function has a domain of all real numbers.

False

The function is undefined for
x=0 since x is in the denominator.

3. The function has a range of {yl-

Statement is unclear but the range is the set of all real numbers except zero.

4. The function is a reflection of y = 3.

False

The function is a reflection in the x axis of the function
g(x)=(3)/(x)

5. The function passes through the point (3,-27).

False

This is false since:


f(3)=-1\\eq -27

Note. As you can see those statements are false, so any of them is true, except item 3 that is unclear.
