5. The # of times a value is the root of a polynomial function
10. and angle measure equivalent to one "radius" length around a circle
12. relation in which each element in the domain corresponds to exactly one element in the range (each x has only one y - the x's do not repeat)
13. there is a gap or brake in the graph (over its domain)
16. the trigonometric function that is equal to the ratio of the side adjacent to an acute angle (in a right-angled triangle) to the hypotenuse.
17. The name for the graph of the reciprocal function
19. A change in the location or specific shape of a parent function, without changing its general shape
21. of a matrix is a special number that can be calculated from a square matrix.
22. set of ordered pairs
23. x's or domain
24. is a rectangular array of numbers or other mathematical objects for which operations such as addition and multiplication are defined.
25. ax^2+bx+c
26. Function is continuous if its hand drawn graph over an interval can be drawn w/o lifting pencil from paper
27. the name for a graph of the quadratic function

1. is a real number. We often use the term scalar in the context of vectors or matrices, to stress that a variable such as is just a real number and not a vector or matrix.
2. set of all x values
3. measures of triangles
4. y's or range (b/c the value of y depends on the value of x)
6. half of the distance between the minumum and maximum output values of a sine or cosine function
7. set of all y values
8. the trigonometric function that is equal to the ratio of the side opposite a given angle (in a right triangle) to the hypotenuse.
9. two trig functions whose angles add to 90 or are complementary. They have the same ratio.
11. a function w/ a finite number of elements
14. The x-values for which f(x)=o
15. a straight line or plane that touches a curve or curved surface at a point, but if extended does not cross it at that point.
18. when the left side of an equation is equal to the right side for all values of the variable for which both sides are defined
20. a mathematical relationship or rule expressed in symbols.
