# Evaluation of a Function

Not what you're looking for?

A certain rational function f(x) contains quadratic functions in both its numerator and denominator. Aside from that, we also know the folliwing things about f:

f has a vertical asymptote at x=5

f has a single x-intercept of x=2

f is removably discontinous at x=1, lim as (x)approaches 1 of f(x)= -1/9

evaluate lim of f(x)as x approaches infinity

Problem:

A certain rational function f(x) contains quadratic functions in both its numerator and denominator. Aside from that, we also know the following things about f:

• f has a vertical asymptote at x = 5

• f has a single x-intercept of x = 2

• f is removably discontinuous at x = 1, since

• Evaluate

Solution:

If f has a vertical asymptote at x = 5, then the factor (x-5) must appear in the denominator but not the numerator. Why is this? When we plug x = 5 into our function f, we want to get a 0 in the denominator but not the numerator; mathematically, this means an asymptote must appear ...
