What is the inverse of the given relation? y = 4x - 8
to inverse a equation make all y's x and andy x's y
Thus the inverse is
x=4y-8
Evaluated to
4y=x+8
y= \(\frac{1}{4}x +2\)
First, switch x and y
x = 4y - 8
Then perform the opposite operations:
x + 8 = 4y
\(\frac{x}{2} + \frac{8}{4} = y\)
\(\frac{x}{2} + 2 = y\)
