Question

Determine the domain and range of the graph. x −10 −5 5 10 y −10 −5 5 10

Answer 1

Domain:

we know that domain is all possible values of x for which any function is defined

we are given all possible x-values as -10 , -5 , 5 , 10

so, domain is {-10, -5, 5,10}

Range:

we know that domain is all possible values of y for which x is defined

we are given all possible y-values as -10 , -5 , 5 , 10

so, range is {-10, -5, 5,10}
