determine the polynomial whoes graph passes through the points:
(2,4),(3,4),(4,4)
as you can see, ycoordinate of each point is same
=> it is a line y=4

There are an infinite # that pass thru the points.

The question is very poorly presented. There is no answer for "THE" polynomial whose graph passes through the three points. There is an infinite number of such polynomials.

Obviously the simplest one is the constant polynomial y=4.

It is easy to find other more interesting polynomials whose graphs pass through those three points.

Note that the polynomial

y+=+%28x-2%29%28x-3%29%28x-4%29

passes through the points (2,0), (3,0), and (4,0). That means the graph of

y+=+%28x-2%29%28x-3%29%28x-4%29%2B4

will pass through the points (2,4), (3,4), and (4,4).

A graph of that third degree polynomial....

And higher degree polynomials that pass through those 4 points can be found simply by adding additional linear factors to the first part of the polynomial. Here is a graph showing the graphs of the previous polynomial and also the fourth degree polynomial

y+=+%28x-1%29%28x-2%29%28x-3%29%28x-4%29%2B4
