Across
- 2. A single fixed number (unlike a variable, whose value can vary).
- 3. A straight line, or an equation or expression whose graph is a straight line. If m and b are constants, then mx+b is a linear expression, and a function f defined by f(x)=mx+b is a linear function.
- 5. The study of mathematical symbols and the rules for manipulating those symbol
- 6. The point on a coordinate plane where the x-axis and y-axis intersect. It is represented by the coordinates (0,0).
- 7. A point on a 2-dimensional plane is described by a pair (x,y). The coordinate x is given by the labels below the grid, and the coordinate y is given by the labels to the left of the grid.
- 11. A constant that a variable or expression is multiplied by.
- 12. A line that you can flip (or reflect) a graph across that results in the same graph.
- 13. A number that is raised to a power.
- 14. The distance a number is from 0.
Down
- 1. The set of inputs (x-coordinates) of a relation or function.
- 4. A grid used to illustrate values of algebraic expressions
- 7. A 2-dimensional flat surface used for plotting points, lines, curves, and regions. It contains an x and a y axis which intersect at the origin.
- 8. In a power, the number of times the base is multiplied by itself.
- 9. A number that is the square of a rational number. For example, 1, 4,25/16 and 0 are perfect squares. An integer is a perfect square only if it is the square of an integer, which can be proven using the fundamental theorem of arithmetic.
- 10. The cube root of a, written 3√a, is the number whose cube is a. That is, (3√a)3=a.
