Question

find the domain and the range of the relation and determine whether its a function {(7,5),(-3,-5)(2,-2),(3,-8)}

Answer 1

the (x,y) the x term in the brakets is yur domain and y is yur range
so here domain = [7,-3,2,3]
range = [ 7,-5,-2,-8]
and for satisfy that it is either function or not then just check that all the numbers in domain must be used and must have only one range
