Answer:
discrete
D {1,2,3,4,5,6,7}
R {5,6,7}
function
Step-by-step explanation:
graph is discrete because it is plotted for some values/numbers of input only
not like a continuous one
D {1,2,3,4,5,6,7} all the inputs
R {5,6,7} output range
A graph becomes a function if for a given x value there is a distinct/one y value
so here it is a function
