Unit 5: Algebra 1

3. The x-values where the function has a value of zero.
4. Expression expression containing a square root.
5. The point where a line meets or crosses the y-axis
8. A function with a constant rate of change and a straight line graph
9. The ratio of the vertical and horizontal changes between two points on a surface or a line.
14. The set of x-coordinates of the set of points on a graph; the set of x-coordinates of a given set of ordered pairs. The value that is the input in a function or relation.
18. With respect to the variable x of a linear function y = f(x), the constant rate of change is the slope of its graph.
20. A rigid transformation of a graph in a horizontal direction, either left or right.

1. a polynomial consisting of three terms or monomials.
2. The change in the value of a quantity by the elapsed time. For a function, this is the change in the y-value divided by the change in the x-value for two distinct points on the graph.
6. A value in a sequence--the first value in a sequence is the 1st term, the second value is the 2nd term, and so on; a term is also any of the monomials that make up a polynomial.
7. For any number x, the numbers that can be evenly divided into x are called factors of x.
10. Any mathematical calculation or formula combining numbers and/or variables using sums, differences, products, quotients including fractions, exponents, roots, logarithms, functions, or other mathematical operations.
11. A nonlinear function in which the independent value is an exponent in the function,as in y=abx.
12. The set of all possible outputs of a function.
13. A number multiplied by a variable in an algebraic expression.
15. The point where a line meets or crosses the x-axis
16. polynomial equation with two terms usually joined by a plus or minus sign
17. Algebraic expressions that include real numbers and variables
19. An equation of degree 2, which has at most two solutions.
