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

inverse

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

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

Solution steps

y = - 2 x^{2} + 4

Replace

x

with

y

x = - 2 y^{2} + 4

Solve for

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

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

f (x) = \frac{2 x}{5 x - 3}

2 π r^{2} + 2 π r h

f (x) = - x^{2} + 20 x - 64

\frac{3}{x - 2} - 1

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