Answers:
Vertical asymptote
x = -4
Step-by-step explanation:
x = a is a vertical line, so when the graph increases or decreases without bound when it approaches x = a, we can say that this line is a vertical asymptote.
A vertical asymptote occurs when the denominator of a rational function is zero. For the function f(x) = 5/(x + 4), the denominaor is 0 when
x + 4 = 0
x + 4 - 4 = 0 - 4
x = - 4
So, the line x = -4 is a vertical asymptote.
