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.
