What is the absolute value of -1+3i

So for example, the absolute value of -3 is 3 and the the absolute value of 3 is 3. In math sense, this would be written as |−3|=3 or |3|=3, where the two vertical bars around a number mean absolute value. Absolute values can also be taken of entire expressions like |5×2−15|, which would come out to be 5 (not -5).

Step-by-step explanation:

step-by-step explanation:

  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.
