inverse of f(x)=3x^2-12x+7

inverse

f (x) = 3 x^{2} - 12 x + 7

\frac{12 + 12 x + 60}{6}, \frac{12 - 12 x + 60}{6}

Solution steps

y = 3 x^{2} - 12 x + 7

Replace

x

with

y

x = 3 y^{2} - 12 y + 7

Solve for

y, x = 3 y^{2} - 12 y + 7

\frac{12 + 12 x + 60}{6}, \frac{12 - 12 x + 60}{6}

h (x) = x^{3} - 3

f (x) = 9 x^{3} - 12

tan (0.05)

\frac{1}{6} x^{2} + 3

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