Question

What is the inverse of the given relation?
y = 4x + 12

Answer 1

9514 1404 393

Answer:

y = 1/4x -3

Explanation:

The inverse relation can be found by interchanging y and x, then solving for y.

x = 4y +12

x = 4(y +3) . . . . factor out 4

x/4 = y + 3

x/4 -3 = y

y = (1/4)x -3 . . . . the inverse relation
