Question

Find the inverse f(x) = 3х^2 - |

Answer 1

Answer:

$f^{-1}$=$\frac{\sqrt{3(x+1)} }{3}$

Step-by-step explanation:

f(x) = 3$x^{2}$ - |

Let y= 3$x^{2}$-1

Both side -1

y+1=3$x^{2}$  

$x^{2}$=    $\frac{\sqrt{3(y+1)} }{3}$

x=  $\frac{\sqrt{3(y+1)} }{3}$

$f^{-1}$=$\frac{\sqrt{3(x+1)} }{3}$
