7.3: Comparing and Describing Functions

Front

What is required to compare two functions?

Back

They must be expressed in the same form.

Front

Which function has the greater rate of change if Function A is represented by an equation and Function B by a graph?

Back

Function B.

Front

Who is going faster based on their rate of change: The Hare or The Tortoise?

Back

The Hare.

Front

What might you need to compare when looking at two functions?

Back

Their rate of change and initial value.

Front

Who has the greater rate of change: Hunter or Casey?

Back

Casey has the greater rate of change.

Front

What is a function?

Back

A relation that assigns exactly one output for each input.

Front

What does the rate of change represent in a function?

Back

The change in the output value divided by the change in the input value.

Front

What is the Vertical Line Test?

Back

A method to determine if a graph represents a function; if a vertical line intersects the graph more than once, it is not a function.

Front

How can you determine if two functions are equivalent?

Back

They produce the same output for every input.

Front

What is the initial value of a function?

Back

The value of the function when the input is zero.
