What is the vertical line test?

Back

The vertical line test is a method used to determine if a graph represents a function. If a vertical line intersects the graph at more than one point, the graph does not represent a function.

Front

How do you find the perimeter of a triangle?

Back

To find the perimeter of a triangle, add the lengths of all three sides together.

Front

What does f(2) mean in function notation?

Back

In function notation, f(2) means to evaluate the function f at the value x = 2.

Front

How do you determine the slope from a table of values?

Back

The slope can be determined by taking the difference in y-values divided by the difference in x-values between two points on the line.

Front

What is a function?

Back

A function is a relation that assigns exactly one output (y-value) for each input (x-value).

What is the y-intercept of a line?

Front

What is the difference between independent and dependent variables?

Back

The independent variable is the input of a function (usually x), while the dependent variable is the output (usually y) that depends on the independent variable.

What does it mean for a graph to be linear?

Back

A graph is linear if it can be represented by a straight line, indicating a constant rate of change.
