Question

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.

Answer 1

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
