With this limit i don’t know what to do at all!

We're given

The function is continuous for all . If a function is continuous, then

This allows us to pass the limit through the square root:

The limit of a quotient is the quotient of limits (provided the limit of the denominator is not 0):

In the numerator, we can distribute the limit as

So we end up with

Then we just solve for the desired limit:

Obviously the limit can't have two values, so one of these is not right, but only the positive value is one of the answer choices, so the limit is 16.

  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.
