Relations vs. Functions
A set of ordered pairs that can be represented as a list, graph, table, or mapping.
What is a relation?
A graph that includes a set of points that cannot all lie on the same line.
What is a non-linear fucntion?
The behavior of a graph as it approaches an infinity.
The solution of a function.
What is a root?
A function written using two or more expressions.
What is a piecewise defined function?
What is a dependent variable?
If a graph increases the same amount every period of time, it is this.
What is a linear function?
Relative maximums and minimums are examples of this.
What is an extrema?
Value in which f(x) = 0.
What is a function's zero?
A piecewise linear function that is made up of undefined line segments.
What is a step function?
A relation where each domain value is paired with exactly one range value.
What is a function?
The letter W is an example of this type of symmetry.
What is line symmetry?
This is the point(s) when a graph crosses the x-axis.
What is a real zero?
A function is this on a portion of its domain where the graph is above the x-axis.
What is positive?
V is an example of this type of function.
What is an absolute value function?
Equations that represent functions are written in this form - y is replaced with f(x).
What is function notation?
The letter s is an example of this type of symmetry.
What is point symmetry?
A point on the graph of a function where no other nearby points have a greater y-coordinate.
What is a relative maximum?
A function that can be graphed with connected lines or smooth curves
What is a continuous function?
A transformation that alters the size but not the shape of a function.
What is a dilation?
Each element of the range corresponds to an element of the domain.
What is an onto function?
This makes x^2 +6 a non-linear function.
What is an exponent?
This is another name for extrema.
What are turning points?
As the x-value increases, the value of the function decreases.
Graphs which have at least one common characteristic.
What is a family of graphs?
