| Term | Definition |
|---|---|
| Arithmetic Sequence | A sequence whose successive terms result from addition of a common difference, d. |
| Asymptote | A line that a graph gets closer to as the value of a variable becomes extremely large or small. |
| Base | The value of b in a function of the form f(x) = abx , where a and b are real numbers with a ≠ 0, b > 0, and b ≠ 1. |
| Constraint | A limitation on the possible values of variables in a model, often expressed by an equation or inequality or by specifying that the value must be an integer. |
| End Behavior | The trends in the y-values of a function as the x-values approach positive and negative infinity. |
| Exponential Decay | An exponential function of the form f(x) = abx in which 0 < b < 1. If r is the rate of decay, then the function can be written y = a(1 - r )t , where a is the initial amount and t is the time. |
| Exponential Function | A function of the form f(x) = abx, where a and b are real numbers with a ≠ 0, b > 0, and b ≠ 1. |
| Exponential Growth | An exponential function of the form f(x) = abx in which b > 1. If r is the rate of growth, then the function can be written y = a(1 + r )t , where a is the initial amount and t is the time. |
| Geometric Sequence | A sequence whose successive terms result from multiplication of a constant ratio, r, where r ≠ 0 and r ≠ 1. |
| Horizontal Translation | A shift of the graph left or right, with no change in the shape of the graph. |
| Infinity | The concept of something that is unlimited, endless, without bound, ∞. |
| Interval Notation | A way of writing subsets of the real number line using endpoints, parentheses, and/or brackets. |
| Recursive Relationship | A sequence in which one or more previous terms are used to generate the next term. |
| Vertical Translation | A shift of the graph up or down, with no change in the shape of the graph. |
| Zero Exponent | For any nonzero real number x, x0 = 1. |
