Sure! Here are short definitions for each of the requested terms:
### Key Features
Key features refer to important characteristics of a function or graph, including:
- **Intercepts:** Points where the graph crosses the axes.
- **Asymptotes:** Lines that the graph approaches but never touches.
- **Maxima and Minima:** Highest and lowest points on the graph.
- **Intervals of Increase/Decrease:** Ranges where the function is rising or falling.
- **End Behavior:** The behavior of the graph as it moves towards positive or negative infinity.
### Asymptote
An asymptote is a line that a graph approaches but never reaches. There are three types:
- **Vertical Asymptotes:** Lines \( x = a \) where the function tends to infinity as it approaches \( a \).
- **Horizontal Asymptotes:** Lines \( y = b \) that the function approaches as \( x \) tends to positive or negative infinity.
- **Oblique (or Slant) Asymptotes:** Lines that the graph approaches at an angle, typically occurring in rational functions where the degree of the numerator is one higher than that of the denominator.
### Domain
The domain of a function is the complete set of possible input values (usually \( x \)-values) for which the function is defined. For example, for the function \( f(x) = \frac{1}{x} \), the domain is all real numbers except \( x = 0 \).
### Range
The range of a function is the complete set of possible output values (usually \( y \)-values) that the function can produce. For example, for the function \( f(x) = x^2 \), the range is all non-negative real numbers (i.e., \( y \geq 0 \)).
