Front

What is the range of a function?

Back

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

Front

What is the domain of a relation?

Back

The domain of a relation is the set of all possible input values (x-values) that can be used in the relation.

Front

What is an independent variable in an experiment?

Back

The independent variable is the factor that is changed or controlled in an experiment to test its effects on the dependent variable.

Front

Calculate the value of the function f(x) = 2x – 1 when x = -2.

Back

f(-2) = 2(-2) - 1 = -5.

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in an experiment, which is affected by the independent variable.

Front

Define a function in mathematics.

Back

A function is a relation that assigns exactly one output value for each input value.

Front

What does it mean for a function to be linear?

Back

A linear function is a function that graphs to a straight line and can be expressed in the form f(x) = mx + b, where m is the slope and b is the y-intercept.

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 a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis).

Front

What is the formula for finding the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).
