Fully Describing Graphs

Define x-intercept.

• The point where a line crosses the x-axis

• The point where a line crosses the y-axis

• The slope of the line

• The y-coordinate of the point where a line crosses the x-axis

What is the y-intercept?

• The point where a graph crosses the x-axis (y=0).

• The point where a graph crosses the y-axis (x=0).

• The highest point on the graph.

• The lowest point on the graph.

What is the definition of slope?

• The rate at which a line rises or falls

• The point where a line crosses the y-axis

• The distance between two points on a line

• The angle between a line and the x-axis

Domain: The set of all possible input values (x-values) for a ________.

• function

• variable

• constant

• equation

What is the definition of 'Range'?

• The difference between the highest and lowest x-values in a function.

• The set of all possible y values in a function.

• Every y value from negative to positive infinity.

• Any value above the origin.

An asymptote is:

• A line that a curve approaches as it heads towards infinity

• A point where two lines intersect

• A curve that never touches the x-axis

• A line that is always parallel to the y-axis

What is the definition of the term 'Vertex'?

• The highest or lowest point on a parabola or an absolute value function.

• A vertical line that splits a function into two mirror opposites.

• An interval of x values for which y values are above the x axis.

• A line that a function approaches but never crosses.

What is the definition of 'Axis of Symmetry'?

• A line that divides a figure into two equal parts

• A point where two lines intersect

• A line that is parallel to the base of a figure

• A point that is equidistant from all sides of a figure

What is the meaning of "end behavior" when talking about a graph?

• The behavior of the graph of a function as x approaches positive or negative infinity

• The initial value of a function

• The maximum value of a function

• The point where the function intersects the y-axis

The x-values where a function equals zero (where the graph crosses the x-axis) are called _______.

• Zeros

• Intercepts

• Extremes

• Asymptotes
