What is a function?

Back

A function is a relation between a set of inputs and a set of possible outputs where each input is related to exactly one output.

Front

How do you determine if a relation is a function?

Back

A relation is a function if no two ordered pairs have the same first element (input) with different second elements (outputs).

Front

What does the notation f(x) represent?

Back

f(x) represents the output of the function f for the input x.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you solve the inequality -3x < 9?

Back

To solve -3x < 9, divide both sides by -3 (remember to flip the inequality sign): x > -3.

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions, showing that one is greater than, less than, or not equal to the other.

Front

What does the graph of y > mx + b look like?

Back

The graph of y > mx + b is a dashed line representing the boundary, with the area above the line shaded.

Front

What is the meaning of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of y when x = 0.

How do you find the value of f(5) if f(x) = 6x?

Back

To find f(5), substitute 5 for x: f(5) = 6(5) = 30.

Front

What is the standard form of a linear equation?

Back

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