What is a function in mathematics?

• A collection of numbers or objects

• A rule that relates one set to another in a specific way

• A rule that assigns each input exactly two outputs

• A graphical representation of data

What does the domain of a function represent?

• The graphical area under the function curve

• The set of all possible input values

• The output values of a function

• The maximum value a function can output

Why is the equation 'y squared equals x' not considered a function?

• Because it only produces negative numbers

• Because it can produce more than one output for a single input

• Because it cannot be graphed

• Because it does not involve any numbers

What is the purpose of the Vertical Line Test?

• To determine if a graph represents a function

• To find the highest point on a graph

• To measure the slope of a line

• To calculate the area under a curve

How is the function notation 'f(x)' interpreted?

• As the division of 'f' by 'x'

• As a function named 'f' with 'x' as the input

• As 'x' subtracted from 'f'

• As the product of 'f' and 'x'
