inverse of ((x^2+21))/9

inverse

\frac{( x ^{2} + 21 )}{9}

9 x - 21, - 9 x - 21

Solution steps

y = \frac{x ^{2} + 21}{9}

Replace

x

with

y

x = \frac{y ^{2} + 21}{9}

Solve for

y, x = \frac{y ^{2} + 21}{9}

9 x - 21, - 9 x - 21

f (x) = 3 - 5 - x

\frac{2 x - 7}{9 x + 4}

f (x) = (5 - x)^{3}

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

f (x) = 4 + tan (π x)
