f(x) has a hole at x = a
The multiplicity of x = a in the numerator is greater than or equal to the multiplicity of x = a in the denominator
f(x) has a vertical asymptote at x = a
x = a is a zero of the denominator and NOT of the numerator OR The multiplicity of x = a in the denominator is greater than the multiplicity of x = a in the numerator

A model is considered appropriate for a data set
The residual plot for the model appears random and without pattern
The value predicted by the model at a certain input gives an overestimate for the true value at that input
The residual for that input is negative
The value predicted by the model at a certain input gives an underestimate for the true value at that input
The residual for that input is positive
The distance between a point on the graph of r = f(θ) and the origin is increasing
Values of r are positive and increasing or values of r are negative and decreasing and |r| (distance) is increasing.
The distance between a point on the graph of r = f(θ) and the origin is decreasing
