domain: {-5, 1, 3, 7}; Yes, it is a function ⇒ 3rd answer
Step-by-step explanation:
Let us revise the relation and the function
∵ 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
