First, give the technology formula for the given function and then use technology to evaluate the function for the given values of x. (Round your answers to four decimal places.)
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,
I 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
