Problem 3. Given the equation for the rational function, r(x) = x+4 x-2 Describe the following (making sure to explain your thinking) a. the domain and range of r(x) b. the y-intercept and any x-intercepts c. r(x)'s end behavior d. asymptotes (including how you can use algebra to show they are there) e. intervals when r(x) is positive, and intervals when it is negative
