Functions and Relations Unit Review

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 based on its domain.

Front

What does f(1) represent in a function?

Back

f(1) represents the output value of the function when the input is 1.

Front

What is the relationship between f(x) and y?

Back

f(x) is another way to express y in the context of a function, where x is the input.

Front

What are ordered pairs in a function?

Back

Ordered pairs are pairs of numbers (x, y) that represent the input and output of a function.

Front

How do you determine the range from a graph?

Back

To determine the range from a graph, identify the lowest and highest y-values that the graph reaches.

Front

What is a function?

Back

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

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) that the function can accept.

Front

What does it mean for a function to be increasing?

Back

A function is increasing if, as the input values increase, the output values also increase.

Front

What does it mean for a function to be decreasing?

Back

A function is decreasing if, as the input values increase, the output values decrease.

Front

What is a linear function?

Back

A linear function is a function that graphs to a straight line and can be expressed in the form y = mx + b.
