In a 2012 survey, 636 male paid employees and 537 female paid employees were asked how many hours they worked in the last week. (Those who said, "I don't know" or "I don't work" were not included in the data set.) Compare the distributions of hours of work for the men and women.

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
