Front

What is the RANGE of a graph?

Back

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

Front

What does it mean for y to be a function of x?

Back

For y to be a function of x, each input value (x) must correspond to exactly one output value (y).

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point in a coordinate system, written as (x, y).

Front

What is the first step in the calculation 3 - 1 + 10?

Back

The first step is to subtract: 3 - 1 = 2.

Front

What is the result of multiplying (x - 3)(x + 10)?

Back

The result is x^2 + 7x - 30.

Front

What is a function?

Back

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

Front

What does it mean if a relation is 'not a function'?

Back

It means that at least one input value corresponds to multiple output values.

Front

How do you determine the range of a function from a graph?

Back

Identify the lowest and highest y-values that the graph reaches.

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input has a single output.

Front

What is the significance of the ordered pair (1, 4) in relation to functions?

Back

(1, 4) can be added to a set of points to ensure that y is a function of x, as it does not repeat the x-value.
