Continuous
Having no breaks
Domain
The set of all inputs of a function
Extrema
The minima and maxima of a function
Integer
A number that is not a fraction or a decimal
Intercept
Point at which a line intersects the x- or y-axis
Interval
A continuous series of values
Irrational Numbers
Numbers that cannot be written as a/b, where a and b are integers and b = 0; any number that cannot be written as a decimal that ends or repeats
Natural numbers
The set of positive integers
Negative Function
A portion of a function where the y-values are less than 0 for all x-values
Positive Function
A portion of a function where the y-values are greater than 0 for all x-values
Rate of change
A ratio that describes how much one quantity changes with respect to the change in another quantity; also known as the slope of a line
Ratio
The relation between two quantities, can be expressed in words, fractions, decimals, or as a percent
Rational number
A number that can be written as a/b, where a and b are integers and b=0; any number that can be written as a decimal that ends or repeats
Real numbers
The set of all rational and irrational numbers
Relative maximum
The greatest value of a function for a particular interval of the function
Relative Minimum
The least value of a function for a particular interval of the function
Slope
Measure of the rate of change of one variable with respect to another variable
Slope-intercept method
Method used to graph a linear equation with this method draw a line using only two points on the coordinate plane
Undefined slope
The slope of a vertical line
Whole numbers
The set of natural numbers that also includes 0
X-intercept
The point at which the line intercepts the x-axis at (x,0)
Asymptote
A line that a graph gets closer and closer to, but never touches or crosses
