Flashcards in Chapter 2 Deck (18):
1

Domain

The set of inputs that are the x values

2

Range

The set of outputs that are the y coordinates

3

Function

A relation in which each element of the domain directly corresponds with an element of the range.

4

How to identify a relation as a function

Check to see if any values of the range share a values of the domain

5

How to identify if it is a function on a graph

Vertical line test.

6

X is the

Independant variable

7

F(x) is the

Dependant variable

8

How to determine varies directly and the constant of variation

Put the relation into fraction form. If the fractions are equal then it varies directly. The constant of variation is the simplified fraction

9

Telling Varies directly by an equation

If you can simplify it to y=ax then it varies directly
Y=ax+2 does not vary directly.

10

Translation

Shifts the graph without changing the shape

11

Reflection

Reflects the graph across an axis.
-fx = across x
F(-x) =across y

12

2f(x)

Vertical stretch

13

1/2F(x)

Vertical compression

14

F(2x)

Horizontal compression

15

F(1/2x)

Horizontal stretch

16

Axis of symmetry

The line that symmetrically divides the graph of an absolute value function

17

Vertex

The point of origin for the graph of an absolute value equation.

18

Relation

A set of pairs of input and output values.
