The picture in the attached figure

we know that
area of the <span>the shaded region=area of rectangle -area of a kite

area of rectangle=(3x+x)*(x+x)----> 4x*2x---> 8x</span>²

area of a kite=(1/2)*[d1*d2]
where d1 and d2 are the diagonals
d1=4x
d2=2x
so
area of a kite=(1/2)*[4x*2x]----> 4x²

area of the the shaded region=8x²-4x²-----> 4x²

the answer is
4x²

A relation is (also) a function if every input x is mapped to a unique output y.

In terms of graphical representation, this implies that a graph represents a function if there doesn't exist a vertical line that intersects the graph more than once. So:

The first graph is exactly a vertical line, so it's not a function.
The second graph represents the function y=x, so it's a function: you can see that every possible vertical line crosses the graph only once.
The third graph is not a function, because you can draw vertical lines that cross the graph twice.
Similarly, in the fourth graph you can draw vertical lines that cross the graph twice
The fifth graph is a function, because every vertical line crosses the graph once
The last graph is a function, although discontinuous, for the same reason.
