Given g(x) = (x+3)/(x-1). Evaluate g(5) and g(2n+1).
Note that fractional answers must be expressed like -5/6, and answers with exponents like (x^2-1)/(x+3). Use lower case letters.and do not use spaces in your answers.

Use linear approximations to estimate 1-√46146. Choose a value of "a" to produce a small error.
Note: Answers should be in decimal form. Up to two decimal places only.
