Graph the equation
y=2x

I can't figure out how to show the actual graph, but top solve the problem, you 
take any x or y value (I like to start at 0) and plug the number into the equation. 

It would be a positive correlation,i'd suggest drawings your axis's first and then add your data range( up to 10 say) then plot your points, it'll be easier to visualise it now:?

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
