inverse of f(x)=2y^2+15

inverse

f (x) = 2 y^{2} + 15

\frac{y - 15}{2}, - \frac{y - 15}{2}

Solution steps

x = 2 y^{2} + 15

Replace

y

with

x

y = 2 x^{2} + 15

Solve for

x, y = 2 x^{2} + 15

\frac{y - 15}{2}, - \frac{y - 15}{2}

f (x) = - x^{- 2} + 1

f (x) = 5 ln (x^{2} + 1) - 2

f (x) = y^{3} + 6

\frac{1}{2 x - 2}

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