8th Ch. 3 Flashcard Review

Front

What does the domain of a function refer to?

Back

The domain of a function refers to the set of all possible input values (X) for the function.

Front

What does the range of a function refer to?

Back

The range of a function refers to the set of all possible output values (Y) that the function can produce.

Front

What is the x-intercept of a graph?

Back

The x-intercept of a graph is the point where the graph crosses the x-axis, meaning the value of Y is 0.

Front

What is the y-intercept of a graph?

Back

The y-intercept of a graph is the point where the graph crosses the y-axis, meaning the value of X is 0.

Front

How do you find the value of a function at a specific point?

Back

To find the value of a function at a specific point, substitute the value of X into the function's equation.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in Y divided by the change in X (rise/run).

Front

What is the equation of a line in slope-intercept form?

Back

Front

What does it mean for a function to be linear?

Back

A function is linear if it can be represented by a straight line on a graph, meaning it has a constant rate of change.

Front

What is the significance of the coefficients in a linear equation?

Back

The coefficients in a linear equation determine the slope and y-intercept of the line.

Front

How do you determine if a point lies on a line?

Back

To determine if a point lies on a line, substitute the x-coordinate of the point into the line's equation and check if the resulting y-value matches the y-coordinate of the point.
