Functions Quiz

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 input 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 output values.

How do you determine if a relation is a function?

• Check if each input value is associated with no output value.

• Check if each input value is associated with more than one output value.

• Check if each input value is associated with multiple output values.

• Check if each input value is associated with only one output value.

What is the difference between a function and an equation?

• A function is used in mathematics, while an equation is used in programming.

• A function relates input to output, while an equation shows equality between expressions.

• A function can be graphed, while an equation cannot be graphed.

• A function can have multiple outputs, while an equation has only one solution.

How do you find the x-intercept and y-intercept of a function?

• Set x = 1 to find the x-intercept and set y = 1 to find the y-intercept.

• Set y = 0 to find the y-intercept and set x = 0 to find the x-intercept.

• Set x = 0 to find the x-intercept and set y = 0 to find the y-intercept.

• Set y = 0 to find the x-intercept and set x = 0 to find the y-intercept.

What is the definition of function?

• Has inputs and outputs
• Every input has only ONE output
• Inputs have different outputs every time
• x-values and y-values
