Linear function of the form f(x) = slope * x + intercept.
slope of linear function
intercept at f(0)
defined domain for the function
Evaluation of the slope = f'(x) with strict checking whether x is within the function's domain.
Evaluation of the slope = f(x) with fuzzy checking whether x is within the function's domain.
Evaluation of z = f(x) with strict checking whether x is within the function's domain.
Evaluation of z = f(x) with fuzzy checking whether x is within the function's domain.
endValue = f(upper endpoint of domain).
startValue = f(lowest endpoint of domain).
