8th Math Semester 1 Final

Front

What is a solution to an equation?

Back

A solution to an equation is a value that makes the equation true when substituted for the variable.

Front

What does it mean if an equation has no solution?

Back

An equation has no solution if there are no values that can be substituted for the variable to make the equation true.

Front

What is a line of best fit?

Back

A line of best fit is a straight line that best represents the data on a scatter plot, showing the trend of the data.

Front

What is a function?

Back

A function is a relation where each input (x-value) has exactly one output (y-value).

Front

How can you determine if a set of values is a function?

Back

A set of values is a function if no x-value is repeated with a different y-value.

Front

What is domain in mathematics?

Back

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

Front

What is set builder notation?

Back

Set builder notation is a mathematical notation for describing a set by stating the properties that its members must satisfy.

Front

What does it mean for a line to be an accurate estimate of best fit?

Back

It means the line closely follows the trend of the data points, minimizing the distance from the points to the line.

Front

What is the range of a function?

Back

The range is the set of all possible output values (y-values) for a function.

Front

What is the difference between one solution, no solution, and infinite solutions?

Back

One solution means there is exactly one value that satisfies the equation; no solution means no values satisfy it; infinite solutions mean there are countless values that satisfy the equation.
