Partial Variation Function

Partial Variation Function

Function defined on the set of real numbers by a relationship of the form y = kx +  b where k and b are non-zero real numbers.

The graph of a partial variation function does not pass through the origin (0,0) of the Cartesian plane, since b ≠ 0.


This is the graph of the function f defined by the rule f(x) = 3x − 4.

The rate of change of this function is 3.
