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

inverse

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

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

Solution steps

y = - 4 x^{2} - 2

Replace

x

with

y

x = - 4 y^{2} - 2

Solve for

y, x = - 4 y^{2} - 2

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

f (x) = \frac{4 x}{3 - 7 x}

f (x) = 6 x - x^{2} - 5

(2, 4), (6, 8)

y + 3 = - \frac{2}{3} (x - 2)

\frac{4}{x - 5} + 2
