What is an even function?

• A function f is even if the graph of f is symmetric with respect to both the x and y-axis.

• A function f is even if the graph of f is symmetric with respect to the y-axis.

• A function f is even if the graph of f is symmetric with respect to the x-axis.

• A function f is even if the graph of f is symmetric with respect to neither the x or y-axis.

What is an odd function?

• Odd functions are symmetric with respect to the neither axis.

• Odd functions are symmetric with respect to the x-axis

• Odd functions are symmetric with respect to the origin

• Odd functions are symmetric with respect to the y-axis

What is an union?

• A union is a set of equations with neither an A or B

• A union is a set of equations with an A and B

• The union of two sets A and B is the set of elements which are in A, in B, or in neither A or B.

• The union of two sets A and B is the set of elements which are in A, in B, or in both A and B.

What is an absolute value function?

• An absolute value function is a function that contains an algebraic expression within absolute value symbols.

• An absolute value function is a function whose graph is a straight line, that is a polynomial function of degree one or zero.

• An absolute value function is a polynomial function with one or more variables in which the highest-degree term is of the second degree.

• An absolute value function is any function which can be defined by a rational fraction, i.e. an algebraic fraction such that both the numerator and the denominator are polynomials.

What is an inverse function?

• an inverse function is a relation between sets that associates to every element of a first set exactly one element of the second set.

• In mathematics, an inverse function is a function that "equals" another function:

• In mathematics, an inverse function is a function that "reverses" another function:

• an inverse function is a lack of relation between sets that associates to every element of a first set exactly one element of the second set.

The function shown in the graph is:

• even

• odd

• neither odd nor even

• both odd and even

What is a vertex?

• The intersection of two line

• The middle point of a line

• The common endpoint of two or more rays or line segments.

• The coefficient in front of a, in a quadratic equation.

What is an Intersection?

• a point or line common to lines or surfaces that intersect.

• a point or line common to lines or surfaces that are parallel.

• an expression of more than two algebraic terms,

• an expression of less than two algebraic terms,

What is a Step Function?

• those whose graph is a straight line

• an algebraic fraction such that both the numerator and the denominator are polynomials.

• a function that increases or decreases abruptly from one constant value to another.

• a function defined by multiple sub-functions, each sub-function applying to a certain interval of the main function's domain, a sub-domain

What does continuous mean?

• A set of data is said to be continuous if the values belonging to the set can take on ANY value within a finite or infinite interval.

• A set of data is said to be continuous if the values belonging to the set cannot take on ANY value within a finite or infinite interval.

• It is a function that is not a continuous curve, meaning that it has points that are isolated from each other on a graph.
