Question

identify the mapping diagram that represents the relation and determine whether the relation is a function {(-3,-7) (-2,-7) (4,-7) (5,-7)}

Answer 1

Yes, Its a function.

Answer 2

Yes, the given relation {(-3, -7) (-2, -7) (4, -7) (5, -7)} is a function.

Explanation:

Given the relation: {(-3, -7) (-2, -7) (4, -7) (5, -7)}

Domain is the set of all possible inputs of a relation i.e { -3, -2 , 4 , 5}

Range is the set of output values of a function i.e, {-7}

The mapping as shown below in the figure;

A function is a relation in which every element of the domain is matched to not more than one element of the range.

In other words, we can say that ,no value of x gets mapped to more than 1 value of y.
