Domain is the set of all the input values or the value of x;
In the given graph, the value of x are; -1,-2,0,1,3,5.... and goes on
thus the domain is in the form of interval from -∞ to +∞
Domain : {- ∞ , + ∞}
Range is the set of all the output value or the value ofx;
In the graph, the center of the graph is (2,4) and it curves downward , which show all the negative value of y;
thus, the value of y lies from -∞ to 4
Range : {-∞, 4}
