| Absolute Value | The distance to 0 on the number line. |
| Asymptote | A line that a graph approaches more and more closely. |
| Average Rate of Change | For a function f, between any two points (x1, f (x1)) and (x2, f (x2)) is the slope of the line through the two points. |
| Axis of Symmetry | The line that passes through the vertex and divides the parabola into two symmetric parts. |
| Best-fitting Line | The line that most closely follows a trend in data. |
| Cubic Function | A nonlinear function that can be written in the standard form ax^3 + bx^2 + cx + d. |
| Distance Formula | Between any two points (x1, y1) and (x2, y2) is sqrt((x2 - x1)^2 + (y2 - y1)^2) |
| Domain | The collection of all input values. |
| End Behavior | The behavior of a function’s graph as x approaches positive infinity or negative infinity. |
| Even Function | A function where f(-x) = f(x), will be symmetric about the y-axis. |
| Function | A rule that etablishes a relationship between two quantities, called the input and the output. For each input, there is exactly one output. |
| Linear Extrapolation | Use of a line or its equation to approximate a value outside the range of two known values. |
| Linear Interpolation | Use of a line or its equation to approximate a value between two known values. |
| Midpoint Formula | Of a line segment with endpoints A(x1, y1) and B(x2, y2) is ((x1+x2)/2, (y1+y2)/2) |
| Odd Function | A function where f(-x) = -f(x), will be symmetric about the origin. |
| Parabola | A U-shaped graph of a quadratic function. |
| Parallel | Two lines in the same plane that do not intersect, they will have the same slope. |
| Perpendicular | Two lines in the same plane that intersect to form a right angle, their slopes will have the negative reciprocals. |
| Quadratic Function | A non-linear function that can be written in the standard form y = ax^2 + bx + c. |
| Range | The collection of all output values. |
| Rational Function | A function that has a rule given by a fraction whose numerator and denominator are polynomials and whose denominator is not 0. |
| Slope | The ratio of the vertical change (the rise) to the horizontal change (the run) between any two points. |
| Slope-intercept Form | A linear equation written in the form y = mx + b, where m is the slope and b is the y-intercept. |
| Square Root Function | A function that contains a square root. |
| Vertex | The lowest or highest point of a parabola. |
