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.

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.

Give an example of an equation that is not a function.

• y = sqrt(x)

• x^2 + y^2 = r^2

• y = |x|

• y = x^2

What is the domain of a function?

• The domain of a function is the set of all possible input values for the function.

• The domain of a function is the set of all possible input values for the function except for zero.

• The domain of a function is the range of the function.

• The domain of a function is the set of all possible output values for the function.

What is the range of a function?

• The range of a function is the set of all possible output values.

• The range of a function is the set of all possible input values except the maximum value.

• The range of a function is the set of all possible input and output values.

• The range of a function is the set of all possible input values.

Can a function have an infinite number of solutions?

• Yes

• Sometimes

• Maybe

• No

How can you represent a function using a graph?

• By plotting points on a coordinate plane.

• By using a bar chart to represent the function.

• By drawing a line connecting the points on the graph.

• By using a pie chart to represent the function.
