Shipping company IPS has shipping rates that are a function of the weight of the parcel. For packages weighing less than or equal to 6 pounds, they charge $ 0.5 per pound. For packages weighing between 6 and 17 pounds, they charge $ 2.25 per pound.

If packages weigh 17 pounds or more, they charge $ 3 per pound. IPS refuses to ship any parcel weighing more than 91 pounds.

There is also a flat fee of $ 3 for all deliveries and an additional fee of $ 3 for all deliveries weighing 17 pounds or more.

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

-2 is the right
