Question

Which of the following must be true for the graph of the function  ? (2 points)

There is:

1. a vertical asymptote at x = 4
2. a removable discontinuity at x = 4
3. an infinite discontinuity at x = 4

Answer Choices:

	III only
	I only
	I, II, and III
	II only

Answer 1

This function has removable discontinuity at x = 4. Answer is II or 2

Let evaluate lim as x → 4 of ^{= lim as x → 4 of (x + 4)/4 = 2.}

^{If set f(4) = 2 our function became continuous at x = 4}
