Here is a function x →x + 6
The inverse of this function is
x →x - 6
Write down the inverse of the function x → x/4.

x →

9514 1404 393

  x → 4x

Step-by-step explanation:

Isolate the right-side 'x' and reverse the arrow.

  x → x/4 . . . . . given

  4x → x . . . . . multiply by 4 to get x by itself on the right

  x → 4x . . . . . reverse the arrow

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
