Is the relation a function? Why?

No! 11, the input, has two outputs which makes it not a function! :)

Step-by-step explanation:

because you cannot get two outputs from a single input in a function to put it simply

if you put 11 or any other number in a function all you can get is only one output either 5 or 8 or any number besides them

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

what’s the question?
