Homework Help: Calculus

Posted by Cat on Tuesday, November 27, 2007 at 2:48pm.

f(x) = (ax+b)/(x^2 - c)
i) the graph of f is symmetric about the y-axis
ii) limit as x approaches 2+ of f(x) is positive infinity
iii) f'(1) = -2

Determine the values of a, b, c


I got that c = 4 from the first i). I'm stuck on the second one because
f(x) = f(-x)
(ax+b)/(x^2 - c) = (-ax+b)/(x^2 - c)
ax+b = -ax+b
1=-1 ????
