It would be much you so do the graphs above show a relation, a function, both a relation and a function, or neither a relation nor a function? can somebody also explain to me how to find either as i am extremely confused on

Well it definitely can't be a function

Step-by-step explanation:

To find out if a graph is a function, you can use the vertical line test. The vertical line test is when you draw a line down the center and if it hits one point, it's a function. But, when it hits more than one point, it's not. In this case, a line would hit more than one point; meaning that they are not functions.

the answer to this is a. a^2 + b^2 = c^2
