inverse of f(x)=(x-1)^2+21

inverse

f (x) = (x - 1)^{2} + 21

x - 21 + 1, - x - 21 + 1

Solution steps

y = (x - 1)^{2} + 21

Replace

x

with

y

x = (y - 1)^{2} + 21

Solve for

y, x = (y - 1)^{2} + 21

x - 21 + 1, - x - 21 + 1

f (x) = \frac{2 + 3 ln ( x )}{4 - ln ( x )}

\frac{6}{s ^{2} - 4}

f (x) = 2 π x^{2} + 4 π x

f (x) = \frac{1}{2 x + 11}

\frac{x + 8}{x - 5}
