Across
- 1. A product of variables and numbers, like 3x or 5x2. A monomial is also sometimes called a term.
- 2. The most common value in a collection, or “modes” if more than one are tied.
- 4. Going up and down.
- 5. A number that measures how steep a line is. It shows the amount of change in the height of the line as you go 1 unit to the right. The slope of the line y=mx+b is m.
- 6. 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.
- 8. A number produced by applying a relation or function to an input.
- 10. The top number or expression in a fraction.
- 12. For a periodic function, the amount of time before it repeats. That is, if f is a periodic function, its period is the smallest possible positive h where f(x+h)=f(x) for every x.
- 13. An observed value minus its estimated value.
Down
- 1. The middle number in an ordered list of data values. If there are an even number of values, the median is halfway between the two middle numbers in the list.
- 3. The shape of the graph of y=x2
- 5. To rewrite an expression in a way that means the same thing but is simpler (or shorter). You can simplify 3x−x+6 into 2x+6.
- 7. An expression or equation in which the highest power of a variable has exponent 2.
- 9. The set of outputs (y-coordinates) of a relation or function.
- 11. The values of x where an expression is zero. These are the x-coordinates of the x-intercepts of the expression’s graph. For a polynomial expression, these are usually called roots.
