Let $$f(x)=\frac{(x-2)^2-9}{3}$$.

The equation y=f(x) is graphed, and the x and y intercepts of the graph are connected to form a polygon. What is the area of that polygon?

The area of the polygon is 13/3.

Thank you for atempting the problem, but I am trying to learn, just an answer is not enough.

Also I double checked and 13/3 is not the correct answer to this problem.

Can someone else please atempt this problem?

I can post my solution, though I do not know if is correct....   I got   area = 32/3 ??

I'm sorry but I checked and 32/3 is not correct.

The hint under the solution says that it is an integer

A good start would be to graph the function and draw the polygon:

The polygon is clearly a triangle, the area of which is given by (1/2)base*height.  The base length is fairly obvious. To get the height, simply find f(0).
