Question

what is the domain? and is it interval or single value ?

Answer 1

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}
