Which table shows a function that is decreasing only over the interval
joja [24]

Answer:

Table 4th is showing the function that is decreasing only over the interval

Step-by-step explanation:

We have been given four tables below:

To determine the function that is decreasing only in the given interval

(-1,\infty)

We will check the values after -1 in all four tables

The table in which values is only  decreasing after -1 will be the table which shows a function is decreasing only.

In table 1 the value of x is increasing

In table 2 and 3 the value is increasing and then decreasing but we will consider only decreasing case

Therefore, Table 4th is correct.
