inverse of f(x)=sqrt(7-2x)-5

inverse

f (x) = 7 - 2 x - 5

- \frac{x ^{2} + 10 x + 18}{2}

Solution steps

y = 7 - 2 x - 5

Replace

x

with

y

x = 7 - 2 y - 5

Solve for

y, x = 7 - 2 y - 5

- \frac{x ^{2} + 10 x + 18}{2}

11

\frac{1 - 2 x}{1 - x}

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

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