8.3 Graphing Reciprocal Functions
Reciprocal Function: has an equation of the form where a(x) is a linear function and a(x) ≠ 0
\\\\ • Domain is limited to values for which the function is defined.
Determine the values of x for which is not defined. Give its domain.
Asymptote: A line which a graph approaches, but never touches. • These lines are shown as dotted on a graph, because they shape the graph, but are not truly a part of it.
A. Identify the asymptotes, domain, and range of the function.
B. Identify the asymptotes, domain and range of the function.
To graph these functions, • graph the horizontal and vertical asymptotes • Plot points on either side of the horizontal asymtote. • Connect the points with a curve, and DO NOT cross the asymptotes.
A. Graph the function State the domain and range.
Graph the function State the domain and range.
A. COMMUTINGA commuter train has a nonstop service from one city to another, a distance of about 25 miles. Write an equation to represent the travel time between these two cities as a function of rail speed. Then graph the equation.
