which relation is a function?

Option Bottom-Right

Step-by-step explanation:

Step 1:  Identify the function

In order to be a function, it must pass the vertical line test.  This means that there is one y-value per x-value.

Option Top-Left -> Doesn't work because there are two y-values at the x-value 0.

Option Top-Right -> Doesn't work because there are two y-values at the x-values -2 and 2.

Option Bottom-Left -> Doesn't work because there are two y-values at the x-values -1.

Option Bottom-Right -> Works because for every y-value, there is only one x-value.

 Option Bottom-Right

Bottom Right

Step-by-step explanation:

in a function, every x value only has one y value

in the top left, the x value 0 has two y values

in the top right, the x values -2 and 2 both have two y values

in top bottom left, the x value -1 has two y values

es una operación aritmética.

step-by-step explanation:

no se que fórmula requiera, pero te puedo decir que es adición. deberías revisar porque tema vas y ver que fórmulas puedes aplicar.
