Consider the function g ( x ) = 20 + x 4 x 2 + x . What monomial function f best approximates the end behavior of g ( x ) = 20 + x 4 x 2 + x ? f ( x ) = What is the end behavior of g ( x ) = 20 + x 4 x 2 + x ? (That is, does g ( x ) increase or decrease without bound as x increases or decreases without bound?) As x , g ( x ) As x , g ( x )
