inverse of f(x)=2x^2+2

inverse

f (x) = 2 x^{2} + 2

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

Solution steps

y = 2 x^{2} + 2

Replace

x

with

y

x = 2 y^{2} + 2

Solve for

y, x = 2 y^{2} + 2

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

f (x) = 5 x

(34, 269), (356, 99)

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

f (x) = \frac{3 x - 9}{8}
