Ihave the most trouble with math what’s the answer? ?

Step-by-step explanation:

The given expression is:

To rationalize the denominator, we multiply both the numerator and the denominator by the radical in the denominator,

The radical in the denominator is

Hence we have to multiply by;

  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.
