inverse of f(x)=((3x^2-2x+7))/(2x+5)

inverse

f (x) = \frac{( 3 x ^{2} - 2 x + 7 )}{2 x + 5}

\frac{1 + x + x ^{2} + 17 x - 20}{3}, \frac{1 + x - x ^{2} + 17 x - 20}{3}

Solution steps

y = \frac{3 x ^{2} - 2 x + 7}{2 x + 5}

Replace

x

with

y

x = \frac{3 y ^{2} - 2 y + 7}{2 y + 5}

Solve for

y, x = \frac{3 y ^{2} - 2 y + 7}{2 y + 5}

\frac{1 + x + x ^{2} + 17 x - 20}{3}, \frac{1 + x - x ^{2} + 17 x - 20}{3}
