Hi

1. Use the fixed point iteration algorithm to approximate the fixed points (if any) of the
following functions to 12 decimal places. Produce a graph of each function and the line
y=x that clearly shows any fixed points.
(a) g(x)=x° – 3x – 2x² + 2
(b) g(x) = cos(sin(x))
(c) g(x) = x² – sin(x + 0.15)
(d) g(x)=x*-cos(x)
