Question

Where is the graph decreasing (give the in the interval of decrease) ?

Answer 1

The function is given to be:

`f(x)=(2x+4)/(x-2)`

The graph of the function is shown below:

On observation from the graph, we can see that the graph is decreasing along all intervals except at the asymptote:

`x=2`

Therefore, the intervals of decrease are:

`(-\infty,2)\text{ }and\text{ }(2,\infty)`

The correct options are the FIRST and FOURTH OPTIONS.
