2.if (x,y)is a point on the graph of f(x) then (x, -y) is also a point on the graph

3.if (x,y)is a point on the graph of f(x) then (-x, -y) is also a point on the graph

I searched everywhere, for the first two I found something about symmetry but I still don't really get what the statement means, I found nothing on the last one
