inverse of f(x)= 2/(sqrt(-x+4))

inverse

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

- \frac{4 - 4 x ^{2}}{x ^{2}}

Solution steps

y = \frac{2}{- x + 4}

Replace

x

with

y

x = \frac{2}{- y + 4}

Solve for

y, x = \frac{2}{- y + 4}

- \frac{4 - 4 x ^{2}}{x ^{2}}

9 sin (x)

f (x) = 2 x^{- \frac{1}{2}}

\frac{1.05}{1 + 100 e ^{- 0.285 t}}

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

f (x) = lo g_{2} (x + 1) + 3
