inverse of f(x)=7-3x^2

inverse

f (x) = 7 - 3 x^{2}

- \frac{x - 7}{3}, - - \frac{x - 7}{3}

Solution steps

y = 7 - 3 x^{2}

Replace

x

with

y

x = 7 - 3 y^{2}

Solve for

y, x = 7 - 3 y^{2}

- \frac{x - 7}{3}, - - \frac{x - 7}{3}

f (x) = - 5

f (x) = \frac{7}{\frac{2}{5} x + \frac{1}{8}}

(- 1.9) (3.3)

\frac{- 3 x + 9}{x ^{2} + x - 12}
