Step-by-step explanation:

Beverly makes wreaths to sell for the fall season. She picked 430 pine cones from the wooded area near her house. If she uses 23 pine cones per wreath, how many wreaths can she make?

430 pine cones = x wreaths

x wreaths = 18.695652174 wreaths

Andrej [43]

Answer:

See attachment

Step-by-step explanation:

The relation that is not a function is shown in the attachment.

For a relation to be a function, it must be either one-to-one or many-to-one.

The relation shown in the attachment is one-to-many relation hence it is not a function.

This is because -5 corresponds to -4 and 3,making the graph of this relation to fail the vertical line test.
