introduction to function and equation
1. Domain and Range of a Relation
In many naturally occurring phenomena, two variables may be linked by some type of relationship. For instance, an archeologist finds the bones of a woman at an excavation site. One of the bones is a femur. The femur is the large bone in the thigh attached to the knee and hip. Table 4-1 shows a correspondence between the length of a woman’s femur and her height.

Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. ... It is also known as the slope and gives the rate of change of the dependent variable.
