It will take 12 people to finish the turkey
Here is how we get the answer....
First, replace f(x) with y . ...
Replace every x with a y and replace every y with an x .
Solve the equation from Step 2 for y . ...
Replace y with f−1(x) f − 1 ( x ) . ...
Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
I think you might be referring to the definite integral,
Recall the definition of absolute value:
Then if , and is . So spliting up the integral at <em>x</em> = 1, we have
The rest is simple:
