Which expression describes the set of numbers given by the interval:

A

Step-by-step explanation:

Looking at the interval, we can see that this includes all of the numbers coming from negative infinity all the way up to -1.

In other words, the set being described here are all the numbers less than or equal to -1.

Another way to write this is all numbers no more than -1.

Thus, our answer is A.

And we're done!

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
