Let f be the function defined for x >> 0 (x is greater or equal 0) with f(0)=5 and f', the first derivative of f, given by f'(x)=e^(-x/4) sin(x^2). The graph of y=f'(x) is shown as the graph -> http://img483.imageshack.us/img483/5387/42521098qj9.png
a) Use the graph of f' to determine whether the graph of f is concave up, concave down, or neither on the interval 1.7 < x < 1.9. Explain
b) On the interval 0 << x << 3 (<< is greater or equal), find the value of x at which f has an absolute max. Justify the answer.
c) Write an equation for the line tangent to the graph of f at x=2
