In Section \ref{ExpEquations} we solved equations and inequalities involving exponential functions using one of two basic strategies. We now turn our attention to equations and inequalities involving logarithmic functions, and not surprisingly, there are two basic strategies to choose from.

Enter the given exponential equation in the line headed “Y 1 =”. Enter the given value forf(x) f(x) in the line headed “Y 2 =”. Press [WINDOW]. Adjust the y-axis so that it includes the value entered for “Y 2 =”. Press [GRAPH] to observe the graph of the exponential function along with the line for the specified value off(x). f(x).

The graph of f(x) should be exponential decay because b < 1. The graph should pass through the point (0, 1) and there should be a horizontal asymptote at the x ­axis. Features of the Graph of Exponential Functions in the Form f(x) = b x or y = b x • The domain of f(x) = b x

Section 6.3 Exponential Functions 307 STUDY TIP The graph of y = abx approaches the x-axis but never intersects it. Graphing Exponential Functions The graph of a function y = abx is a vertical stretch or shrink by a factor of ∣ a ∣ of the graph of the parent function y = bx.When a < 0, the graph is also refl ected in the x-axis.The y-intercept of the graph of y = abx is a.

EXPONENTIAL FUNCTIONS Determine if the relationship is exponential. If so, determine a function relating the variable. > Is it exponential? no What is the starting point (a)? What is the common ratio (B)? Write the equation in y=a(B)x form: x y 1 26 2 24 3 22 4 20 5 18 > > 22÷24 = .917 20÷22 = .909 > 18÷20=.9 24÷26 = .923

Writing Exponential Equations from Points and Graphs. You may be asked to write exponential equations, such as the following: Write an equation to describe the exponential function in form $$y=a{{b}^{x}}$$, with a given base and a given point. Write an exponential function in form $$y=a{{b}^{x}}$$ whose graph passes through two given points.
