Answer

f^{-1}(x) = \frac{3 - 2x}{-4x + 3} Explanation 1. Swap f(x) and x Set y = \frac{-3x+3}{-4x+2}, then swap to x = \frac{-3y+3}{-4y+2}. 2. Solve for y Multiply both sides by (-4y+2): x(-4y+2) = -3y+3. 3. Expand and collect y terms -4xy + 2x = -3y + 3; bring y terms together: -4xy + 3y = 3 - 2x. 4. Factor and isolate y y(-4x + 3) = 3 - 2x; so y = \frac{3 - 2x}{-4x + 3}.

Explanation

1. Swap $f(x)$ and $x$<br /> Set $y = \frac{-3x+3}{-4x+2}$, then swap to $x = \frac{-3y+3}{-4y+2}$.<br />2. Solve for $y$<br /> Multiply both sides by $(-4y+2)$: $x(-4y+2) = -3y+3$.<br />3. Expand and collect $y$ terms<br /> $-4xy + 2x = -3y + 3$; bring $y$ terms together: $-4xy + 3y = 3 - 2x$.<br />4. Factor and isolate $y$<br /> $y(-4x + 3) = 3 - 2x$; so $y = \frac{3 - 2x}{-4x + 3}$.
