Front

What does it mean when a function g(x) is shifted up 2 units compared to f(x)?

Back

It means that every point on the graph of g(x) is 2 units higher than the corresponding point on the graph of f(x).

Front

What is a function?

Back

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

Front

What is the domain of a function?

Back

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

Front

What is the slope of a linear function?

Back

The slope is a measure of the steepness of a line, calculated as the change in y divided by the change in x.

How do you determine the range from a set of ordered pairs?

Back

Identify all the unique y-values from the ordered pairs.

Front

What does the equation y = mx + b represent?

Back

It represents the slope-intercept form of a linear equation, where m is the slope and b is the y-intercept.

Front

What is the significance of the y-intercept in a linear function?

Back

The y-intercept is the point where the graph of the function crosses the y-axis.

Front

If f(x) = x and g(x) = x + 2, what is the relationship between f and g?

Back

g is a vertical translation of f, shifted up by 2 units.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers (x, y) that represent a point in a coordinate system.
