Question

if f(x)= x-2 / x+1 , then f(n+1) equals what?

Answer 1

f(n+1) =

(n+1) - 2
-------
(n+1) + 1

Answer 2

might wanna simplify it...

Answer 3

\[(n(n+3)/(n+1)\]

Answer 4

??? you sure bout that ???

Answer 5

i chose n+2-2/ n+1+1 and it was wrong so i think it is the other one

Answer 6

n+2-2 ?? that aint right

(n+1) - 2

Answer 7

Just simply replace x with n
f(n) = n-2/n+1

f(n+1)= n-1/n+2

Answer 8

Sorry. I used the incorrect function syntax in a program solver.
\[((n+1)-2)/((n+1)+1)=(n-1)/(n+2)\]
amistre64 and sstarcia are correct.
