The graph shows the production of cars per day at a factory during a certain period of time. what is the domain of this function during this period?

graph of days versus cars. points are plotted at the following coordinates: 0 comma 0, 1 comma 50, 2 comma 100, 3 comma 150, 4 comma 200, 5 comma 250, 6 comma 300, 7 comma 350, 8 comma 400, 9 comma 450.

the domain is all real numbers 0 through 9.
the domain is all integers 0 through 9.
the domain is all positive real numbers.
the domain is all positive integers.

yes. we do proportions in probabilities.

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
