What is a function?

Back

A function is a relation between a set of inputs and a set of possible outputs where each input is related to exactly one output.

Front

What is the vertical line test?

Back

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

Front

What is the square root of 108 simplified?

Back

6√3

Front

What is an x-intercept?

Back

The x-intercept is the point where a graph crosses the x-axis, meaning the value of y is zero at that point.

Front

What is a y-intercept?

Back

The y-intercept is the point where a graph crosses the y-axis, meaning the value of x is zero at that point.

Front

What does the domain of a function represent?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

What does a negative association in a graph indicate?

Back

A negative association indicates that as one variable increases, the other variable tends to decrease.

Front

How do you find the slope of a linear function?

Back

The slope of a linear function can be found by taking the difference in y-values divided by the difference in x-values between two points on the line.

Front

What is the standard form of a linear equation?

Back

The standard form of a linear equation is Ax + By = C, where A, B, and C are integers, and A should be non-negative.

Front

What is the difference between independent and dependent variables?

Back

The independent variable is the variable that is changed or controlled in an experiment, while the dependent variable is the variable that is measured or affected.
