Equations and Functions

What is the difference between an equation and a function?

• An equation is a mathematical statement, while a function is a mathematical operation.

• An equation shows equality between two expressions, while a function is a relation between inputs and outputs.

• An equation can have multiple solutions, while a function has a unique output for each input.

• An equation represents a single value, while a function represents a range of values.

How can you determine if an equation represents a function?

• Check if each input value has no output value.

• Check if each input value has multiple output values.

• Check if each input value has more than one output value.

• Check if each input value has exactly one output value.

One type of redwood tree has an average height of 65 feet when it is 20 years old. If the tree is more than 20 years old, the average height, h, can be modeled by the function h = 1.95(a − 20) + 65, where a is the age of the tree in years. Which statement about this situation is true?

• Every additional 1.95 ft of length over 20 ft adds 45 years to the age of this type of redwood tree.

•  For this type of redwood tree, the average height increases by 1.95 ft per year throughout its lifetime.

• Each additional year of age over 20 years adds 1.95 ft to the average height of this type of redwood tree.

•  For this type of redwood tree, the average height increases by 65 ft for every 20 years of growth.

What is the vertical line test?

• The vertical line test is a method used to determine if a relation is symmetric.

• The vertical line test is a method used to determine if a relation is a function.

• The vertical line test is a method used to determine if a relation is continuous.

• The vertical line test is used to determine if a relation is linear.
