Inverses Generally
In previous sections, you have explored how the multiplicative inverse of a
slope creates a line that is perpendicular to the line the slope defines. When a
function is the inverse of another function, the situation differs. In such a case,
as Figure 7.10 illustrates, the values of the
x
and
y
coordinates that make up the
Figure 7.10
Equations that are the inverse of each other generate inverted ordered pairs.
