Title

A necessary, must have part, that appears at the top of the graph, displaying what the data is about.

dependent variable

the measure of change in the independent variable

independent variable

the tested varaible

Intervals

Literally "between values". An interval is a set of numbers between 2 numbers a and b and possibly including a, or b, or both.

Series

sum of the terms of a sequence

key

A box that identifies symbols or lines on a graph.

Domain

The ______________________ is all the possible INPUT, X, values.

Range

The difference between the greatest number and the least number in a set of data.

Root/zero

where function crosses x axis; x-coordinate where function equals zero

y-intercept

the point where the line crosses the y-axis

Continuity

Refers to whether a function contains holes, jumps, or breaks

increasing

ƒ'(x)>0

decreasing

ƒ'(x)<0

Local maximum point

a point on the function that is greater than or equal to surrounding points

Local minimum point

a point on the function that is less than or equal to surrounding points.

Absolute/global maximum

the largest point on the function; a point on the function that is greater than or equal to all other points on the function

Absolute/global minimum

the smallest point on a function; a point on the functions that is less than or equal to all other points on the function

horizontal asymptote

a line that the curve approaches as x goes to infinity but never reaches

vertical asymptote

comes from a factor in the denominator that doesnt cancel out

concave up

When f '(x) is increasing, f(x) is

concave down

When f '(x) is decreasing, f(x) is

point of inflection

When f '(x) changes from increasing to decreasing or decreasing to increasing, f(x) has a

A function is even

if you can substitute a -x for every x in the function, simplify, and get back the exact original function.

A function is odd

if you can substitute a -x for every x in the function, simplify, and get back the exact opposite of the entire function. i.e. all the signs have changed!

y axis

has the dependent variable, the vertical line on a graph

Graph Title

tells what graph is about

line graph

shows change over time

Bar graph

Bars do not touch; categorical data is typically on the horizontal axis; to describe: comment on which occurred the most often or least often

circle graph

compares percents, fractions or decimals; another name for pie chart

Quantitative Data

Measurements that are recorded on a naturally occurring numerical scale.

Qualitative Data

Measurements that cannot be measured on a natural numerical scale; they can only be classified into one of a group of categories.

x axis

The horizontal axis on a coordinate graph, for the varaible that controls the other (an axis ia a line on a graph)

manipulated variable

another name for independent variable

responding variable

another name for dependent variable

MIX

acronym for Manipulated, Independent, X axis

DRY

acronym for Dependent, Responding, Y axis

increments

Evenly spaced units; the axis of a graph must use proper _______________
