We have the following function:
The graph of this function has been plotted below. So lets analyze each statement:
1. The function is always increasing. FalseAs you can see x increases from -∞ to 0 and decreases from 0 to +∞
2. The function has a domain of all real numbers. FalseThe function is undefined for
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. FalseThe function is a reflection in the x axis of the function![g(x)=\frac{3}{x}](/tpl/images/0121/9515/9b6c7.png)
5. The function passes through the point (3,-27).FalseThis is false since:
Note. As you can see those statements are false, so any of them is true, except item 3 that is unclear.
