W/c one of the ff is the invers of f(x)=2+e^x+1

Step-by-step explanation:

   To find the inverse of a function , we swap and solve the equation to get the form . This is the inverse function.

On swapping in , we get .

∴ is the inverse function.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
