Consider the relation given by the equation y = 2x - 3. The relation of a function with a domain and codomain is specified as follows:
Domain: {0, 1, 2, 3, 4, 5}
Codomain: {-5, -3, -1, 1, 3, 5}
Which of the following statement is correct?

Question

Consider the relation given by the equation y = 2x - 3. The relation of a function with a domain and codomain is specified as follows:

Domain: {0, 1, 2, 3, 4, 5}

Codomain: {-5, -3, -1, 1, 3, 5}

Which of the following statement is correct?

Answer

No, it isn't a function as  the codomain is not specified correctly.

Answer

It is not defined for all values in the domain, so it is not a function.

Answer

It is a function.

Answer

It is not a function as it maps multiple values from the domain to the same value in the codomain.
