probably a stupid question or maybe i'm just doing something wrong but anyways…

OpenStudy (anonymous):

I want to find the corresponding y-coordinate to x=2.50 in the function f(x)=7arctan(x+1) - ln(x^2+2x+2). According to the graph it is suppose to be 6.46, but i get a ridiculous number… can someone explain? maybe i'm plugging it into the formula wrong?
