Answer:
Step-by-step explanation:
Make sure you use the Zero Product Property to solve for each factor when the equation is set equal to 0 and can be factored.
Answer: A slant or oblique asymptote.
Explanation:
When a function is a rational function whose denominator is one degree lower than the numerator, a slant or oblique asymptote occurs when the function is graphed.
Example:
Consider the rational function
y = (2x² + 2x + 3)/(x + 1)
The degree of the numerator is 2, and the degree of the denominator is 1 so that the degree of the numerator is one higher than that of the denominator.
After long division, obtain
2x
-----------------------
x+1 | 2x² + 2x + 3
2x² + 2x
-------------------
3
That is,
(2x²+2x+3)/(x+1) = 2x + 3/(x+1)
As x -> ∞, 3/(x+1) -> 0, and the curve behaves as the straight line y = 2x.
The curve, therefore, approaches the straight line with a slope of 2.
For this reason, it is called a slant or oblique asymptote.
The graph of this function is shown below to illustrate the concept.
