inverse of f(x)=f(x)=49-x^2

inverse

f (x) = f (x) = 49 - x^{2}

- x + 49, - - x + 49

Solution steps

y = 49 - x^{2}

Replace

x

with

y

x = 49 - y^{2}

Solve for

y, x = 49 - y^{2}

- x + 49, - - x + 49

f (x) = f (x) = 6 x - 5

\frac{- 4 x}{7}

f (4) = - 2 x + 5

f (x) = \frac{- 3 x - 3}{2 x - 14}

f (x) = ln (- 2 x) + 1
