No-argument constructor

Methods

o functionValue 
public double functionValue(double u)
Returns the function evaluated at the given value

Parameters:
u - The x-value at which the function will be evaluated
Returns:
The value of the function at u.
Overrides:
functionValue in class MathFunction
o randomChoice 
public double randomChoice(double a,
                           double b)
Picks a random number between the given parameters

Parameters:
a - The lower bound for the interval from which the random number is chosen
b - The upper bound for the interval from which the random number is chosen
Returns:
A random number between a and b
o randomize 
public void randomize()
This method will select random values for the parameters used to construct the random piecewise linear function
