inverse of f(x)=(x^2-5)/4

inverse

f (x) = \frac{x ^{2} - 5}{4}

4 x + 5, - 4 x + 5

Solution steps

y = \frac{x ^{2} - 5}{4}

Replace

x

with

y

x = \frac{y ^{2} - 5}{4}

Solve for

y, x = \frac{y ^{2} - 5}{4}

4 x + 5, - 4 x + 5

f (x) = 8 x - 8

f (x) = - 2^{x}

- x^{2} + 6 x + 1

1000 x^{3}

f (x) = \frac{1 - 6 x}{1 + 7 x}
