is the following relation a function?
x y
1 4
−1 −2
3 10
5 16
yes
no
yes or no?

Yes this is a function..

Step-by-step explanation:

We have to see the inputs and outputs for the function.

Here x represents input and y represents output.

For a relation to be a function there should be no repition in domain or input of the function i.e. every element in domain should be unique.

The domain for given relation is:

{1,-1,3,5}

All the inputs are only once mapped to the output so this relation is a function ..

the perimeter is increased by a factor of 2

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
