what is the linear function equation represented by the graph?
f (x) =

Sure, let me help you on this one!

Linear functions are written in the following format.



Let's break this up! (Helpful image attached)

Now, it should be easy for you what to place where.

As we can see on the graph, slope of this graph is 1/3, meaning that for every 3 units it goes on the run, it goes 1 unit upwards on the rise.

We can also see y-intercept coming through -4, so let's mark it as well.

Let's write the final answer!

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.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
