1) f(x) = -13/(1 +x^2 )

The question is to find the antiderivative. I'd assume it would be inverse tangent X -13. Am I correct?


2) (1 pt) Given that the graph of f(x) passes through the point (5,5) and that the slope of its tangent line at (x,f(x)) is 4x +5 what is f(3)?

1. No. Try . Do you see why?

2. . Substitute (5, 5) to get the value of C. Then substitute x = 3 to get the required value of y.

I think he meant "inverse tangent times -13"

Hmmmph .... That's what I tell my bank teller every time I bank a cheque for say $30.50 ..... "I think she meant $3050", I say ..... It doesn't work with bank tellers and it doesn't work examiners .... Examiners don't play guessing games, careless mistakes can be costly.
