Consider the function f(x) =x/x^2+1
(a) Find all values ofxfor which f(x) is positive or negative.
Discuss the behaviour of f(x) as x gets very large (in both the
positive and negative direction).
(b) Draw a sign diagram clearly showing the values of x for
which f(x) is increasing and decreasing. Hence find the critical
points off(x) and determine their nature.
(c) Draw a sign diagram clearly showing the values of x for
which f(x) is concave up and concave...
