Prove that if n is an integer, then n2 3n + 5 is odd.

Step-by-Step Solution:
Step 1 of 3

Section 2.2­3.2: 1) Radicals and Power functions reflect over the line y=x; Radicals start increasing at a faster pace and then start to even out, where power functions start increasing slowly then more rapidly. 2) Smaller Inputs have larger Radicals, where larger inputs have larger power functions. a) The product, quotient, and power rule of Radicals do not work if the radicals have more than one term. 3) If the domain or range of the radical functions are (negative infinity, negative infinity) it stays the same. 4) For polynomial and Rational power inequalities/equations you need to factor the equation down until you find the zeros. 5) The domain of rational functions is found by breaking t
