Inverse Functions Horizontal Line TestA function is one-to-one if and only if no horizontal line intersections it graph more than once. Domain = independent variable = possible values of x in f(x) Range = Dependent variable = possible solutions to f(x) Tangent and Velocity The Slope of the tangent line is the limit of the slopes of the secant lines A. The limit of f(x) as x approaches a, equals L B. f(x) approaches L as x approaches a.
