Answer 1

7)

The ordered pairs are:

(-4, -2), (-2, 1), (0, -1), (-3, 0), and (-3,2)

Domain = {-4, -3, -2, 0}

Range = {-2, -1, 0, 1, 2}

A function must map every element of the domain to a unique number in the range

But here -3 is mapped to 0 and 2.

Hence it is not a function

8)

The ordered pairs are:

(-2, 3), (-1,-1), (0,-1), (1,-3), (3, 1)

Domain = {-2, -1, 0, 1, 3}

Range = {-3, -1, 1, 3}

In this case, every element of the domain is mapped to a unique

ut -The ordered pairs are:
