What is the complex conjugate of 12i ?

The conjugate of given complex number is ~

Conjugate of a complex number is the same number with its imaginary part having opposite sign.

Eg. if z = a + i b

Then it's Conjugate = a - i b

  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.

9 x 8 divided by (5-3)=36
