NEED HELP ASAP!! Find a two-variable identity by incorporating a second variable, y, into the single-variable identity. Note that x > 1, x > y, and x and y are positive integers. (x2 − y2)2 − (2xy)2 = (x2 + y2)2 (x2 + y2)2 + (2xy)2 = (x2 − y2)2 (x2 − y2)2 + (2xy)2 = (x2 + y2)2 (x2 − y2)2 + (2xy)2 = (x2 − y2)2

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

pls ask

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
