Semester Review Pt. 3

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis. It is represented as (0, b) where b is the value of the y-intercept.

Front

What is the domain of a function?

Back

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

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

How do you find the zero of a function?

Back

The zero of a function f(x) is the value of x for which f(x) = 0. It is the x-intercept of the graph.

Front

What is the slope of a line?

Back

The slope of a line measures the steepness and direction of the line. It is calculated as the change in y divided by the change in x (rise/run).

Front

What does it mean for a function to be linear?

Back

A linear function is a function that can be graphically represented as a straight line. It has the form f(x) = mx + b, where m is the slope and b is the y-intercept.

Front

What is a system of linear equations?

Back

A system of linear equations is a set of two or more linear equations with the same variables. The solution is the point(s) where the equations intersect.

Front

What is the difference between independent and dependent variables?

Back

The independent variable is the variable that is manipulated or changed, while the dependent variable is the variable that is measured or observed.

Front

What is a function?

Back

A function is a relation that assigns exactly one output value for each input value. It can be represented as f(x).

Front

What is the significance of the point (0,0) in a coordinate plane?

Back

The point (0,0) is known as the origin. It is the point where the x-axis and y-axis intersect.
