Naming Functions

What is a rule that assigns exactly one output to ever input? 

• mapping diagram

• table 

• function

• function notation 

What type of function is shown?

• absolute value

• quadratic

• linear

• exponential

What type of function is shown?

• linear

• quadratic

• square root

• absolute value

Which parent function matches the graph?

• y = |x|

• y = ∛(x)

• y = x²

• y = a⋅b^x

Function or not? (a)  

Domain =​ (b)  

Range =​ (c)  

• Function

• Not a Function

• {-5, -2,  2}

• {-4, 1. 3}

Answer explanation

The relation is not a function because it assigns multiple outputs to at least one input. The domain is {-5, -2, 2} and the range is {-4, 1, 3}, confirming the correct choices.
