Least to greatest..pls

The list that shows the numbers ordered from least to greatest is:

Step-by-step explanation:

To identify what is the least number or the greatest number in the list, first, we're gonna show all the numbers in their decimal form:

Now, we must to identify the least number in the list, as you can see, it's 0.7071067812, more or less 0.71, by this reason must be the first number, the next number is 0.7853981634, more or less 0.79, so must be the second number, the third number can't be because 0.833333333 is greatest than 0.8, so the third number is 0.8 and the last number is in the ordered list from least to greatest, and the option give us that order is the A option.

  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.
