Study Notes
Limits of Rational Functions
- As (x) approaches 1, the left limit of (f(x) = \frac{(x - 1)(x + 5)}{(x - 2)(x - 4)}) evaluates to 2, while the right limit also evaluates to 2.
- For (f(x) = \frac{(x - 1)(x + 2)}{(1 - 2)(1 - 4)}), the left limit approaches -∞ and the right limit approaches -∞.
- The left limit of (f(x) = \frac{-2(x + 3)(x + 1)}{(x - 1)^2}) approaches -∞, and the right limit also approaches -∞.
Identifying Holes and Asymptotes
- For (y = \frac{(x + 3)(x - 2)}{(x + 3)^2}), there is a hole at (x = -3) and a vertical asymptote at (x = -1).
- For (k(x) = \frac{(x + 7)(x + 2)}{(x + 1)(x + 2)}), identify no hole due to the absence of common factors in numerator and denominator.
- The vertical asymptote in (k(x)) is at (x = -1).
- (r(x) = \frac{x^2 - x}{x^2(x - 1)}) has a hole at (x = 1) and a vertical asymptote at (x = -1).
Solving Inequalities
- The inequality (x - 3 \leq 0) has solution ( (-\infty, 3] ).
- The inequality ((x - 1)(x + 2) \geq 0) has solution ([-2, 1)).
Limit Behavior of Graphs
- As input values decrease without bound for (f(x)), the limit approaches -∞.
- For (g(x)), as input values increase without bound, the limit approaches 1.
Analyzing Graphs
- Limit of (h(x)) approaches -∞ as (x) approaches values near the graph from the left and also tends to a finite value as input increases.
- The function (k(x)) has a limit approaching -2 as (x) approaches a certain value from the left.
Summary of Function Behavior
- (f(x)) and (g(x)) both stabilize at a limit of 1.
- Horizontal asymptotes and behavior at infinity show functions approaching fixed value limits across specified intervals.
- Continuous consideration of holes and vertical asymptotes is crucial for understanding graph behavior of rational functions.
Notable Functions and Their Limits
- (f(x) = \frac{2x^2 - 2x + 1}{3x^2 + 5x + 7}) indicated a left limit of 1.
- The graphs of (h(x)) and (k(x)) demonstrate distinct limits based on their structural forms and asymptotic behavior.
Analyzing Output Values
- There are descriptions connecting input values to output limits, emphasizing continuity and variability in rational function graphs.
