Back

The y-intercept is the point (0, 3).

Front

How do you determine the domain of a graph?

Back

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

Front

What is the domain of the graph if it is defined for -4 ≤ x ≤ 3?

Back

The domain is -4 ≤ x ≤ 3.

Front

What does it mean if a system of equations has no solution?

Back

It means the lines represented by the equations are parallel and never intersect.

Front

Solve the system of equations by elimination: 7x + y = -9 and -3x - y = 5. What is the solution?

Back

The solution is (-1, -2).

Front

What is the range of a function?

Back

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

Front

What is the range if it is defined as y ≤ 6?

Back

The range is all y-values less than or equal to 6.

Front

What is the difference between domain and range?

Back

Domain refers to x-values, while range refers to y-values.

Front

What is the range of the function if it is defined as -2 ≤ y < 1?

Back

The range is all y-values from -2 to just below 1.
