inverse of f(x)=(x-1)(x-7)

inverse

f (x) = (x - 1) (x - 7)

4 + x + 9, 4 - x + 9

Solution steps

y = (x - 1) (x - 7)

Replace

x

with

y

x = (y - 1) (y - 7)

Solve for

y, x = (y - 1) (y - 7)

4 + x + 9, 4 - x + 9

f (x) = 5 x^{4} - x^{5}

\frac{x + 8}{x ^{2} - 5 x - 24}

\frac{1}{x} - 3

f (x) = arccos (x)

f (x) = 12 - 2 e^{- x}
