Question

The average cost A to manufacture x items is modeled as A = 5+x/x, where A is expressed in dollars. which statement about function A is true?
a) the vertical asymptote lies at x = -5
b) the horizontal asymptote lies at A = 1
c) the vertical asymptote lies at x = -5
d) the horizontal asymptote lies at A = 2
e) the average cost of manufacturing very large items is almost $5

Answer 1

The horizontal asymptote lies at A = 1. There is no possible way for A to equal one; this is the definition of an asymptote.
