Question

Andre has 45 sheets of paper and needs to buy more. A store has 5 reams of paper, and each ream contains 500 sheets of paper. The number of sheets of paper Andre has after purchasing x reams is represented by a function.f(x)=500x+45What is the practical domain of the function?
a. all integers from 1 to 5, inclusiveb. all real numbers from 1 to 5, inclusivec. {545, 1045, 1545, 2045, 2545}d. all real numbers

Answer 1

Answer:

c. {545, 1045, 1545, 2045, 2545}

Step-by-step explanation:

Domain of a function is a set consisting of all the possible outcomes of the variable.

f(x)=500 x+45       where x= 1,2,3,4,5

the possible outcomes for this function are:

f(1)=500(1)+45= 545

f(2)=500(2)+45= 1045

f(3)=500(3)+45= 1545

f(4)=500(4)+45= 2045

f(5)=500(5)+45= 2545
