domain: {-5, 1, 3, 7}; Yes, it is a function ⇒ 3rd answer

Step-by-step explanation:

Let us revise the relation and the function

  • A relation is a set of inputs and outputs, where the set of inputs is the domain of it and the set of outputs is the range of it
  • A function is a relation with one output for each input, (every input has only one output), where the set of inputs is the domain of it and the set of outputs is the range of it

∵ The relation is {(-5, 2), (7, 7), (3, 6), (1, 7)}

∴ The inputs are: -5 , 7 , 3 , 1

∴ The outputs are: 2 , 7 , 6

∵ The domain is the set of the inputs

∴ The domain of the relation is {-5 , 1 , 3 , 7}

∵ The input -5 has the output 2

∵ The input 7 has the output 7

∵ The input 3 has the output 6

∵ The input 1 has the output 7

∴ There are one output for each input

∴ The relation is a function

domain: {-5, 1, 3, 7}; Yes, it is a function
