what are the open intervals of increase for the given rational function below? f(x)=x - 2/x² - 2x. no intervals of increase exist for this function. (-∞,0)∪(0,2)∪(2,∞) (-∞,0)∪(0,∞) (-∞,∞)
Answer
Explanation:
Step1: Simplify the function
First, factor the denominator: $f(x)=\frac{x - 2}{x(x - 2)}=\frac{1}{x},x\neq0,2$.
Step2: Find the derivative
The derivative of $y = \frac{1}{x}=x^{-1}$ using the power - rule $(x^n)'=nx^{n - 1}$ is $y'=-x^{-2}=-\frac{1}{x^{2}}$.
Step3: Determine where the derivative is positive
Since $y'=-\frac{1}{x^{2}}<0$ for all $x\neq0$, the function has no intervals where it is increasing.
Answer:
No intervals of increase exist for this function.
