r(x) = 4x2 + 1/4x2 − 1; x = −1, 0, 1, ..., 9

f(6)=

f(7)=

For f(6), I got 1.0103, but it is wrong

For f(7), I got 1.0102, but it is wrong

I don't know what I did wrong.

Thank you.

**Reiny**, Sunday, February 5, 2012 at 1:18pmI will assume you meant

f(x) = (4x^2 + 1)/(4x^2 - 1)

f(6) = 145/143 = 1.013986 = 1.0140

f(7) = 197./195 = 1.01025641 = 1.0103

each rounded to 4 decimals
