What’s the inverse of <br> f(x) = -2 + 2/3x

saveliy_v [14]

So the steps to find the inverse are:

Change f(x) to y
Switch the positions of x and y
Solve for y
Change y to f^-1(x)

$f(x)=-2+ \frac{2}{3}x\\\\y=-2+ \frac{2}{3}x\\\\x=-2+ \frac{2}{3}y$

Now let's solve for y as such:

$x=-2+ \frac{2}{3}y \\\\x+2=\frac{2}{3}y\\\\\frac{3}{2} (x+2)=y\\\\\frac{3}{2}x+3=y\\\\\frac{3}{2}x+3=f^{-1}(x)$

<u>Your inverse is f^-1(x) = 3/2x + 3</u>
