What is a function?

Back

A function is a relation where each input (x-value) has exactly one output (y-value).

Front

Which of the following mappings represents a function? {1 → 2, 1 → 3, 2 → 4}

Back

This mapping is not a function because the input '1' has two different outputs.

Front

Evaluate f(2) if f(x) = x^2 - 4x + 4.

Back

f(2) = 0.

Front

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

Back

The point-slope form is given by y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.

Front

Which of the following relations is a function? {(1, 1), (2, 2), (3, 3)}

Back

This relation is a function because each input has exactly one output.

Front

What is the slope of the line represented by the equation y - 3 = 4(x - 2)?

Back

The slope is 4.

Front

What does the inequality -7 ≤ 4x + 1 < 5 represent?

Back

It represents a range of values for x that satisfy both parts of the inequality.

Front

Which number is not in the solution to the inequality (-7 ≤ 4x + 1 < 5)?

Back

1 is not in the solution.

Front

How do you determine if a relation is a function?

Back

Check if each input corresponds to exactly one output.

Front

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers.
