Exponential functions in general form, f(x) = ab x, where b>0, have the following properties: The domain of f is all real numbers.; The y-intercept of f is the point (0, a).; The graph of f has ...

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

The same rules apply when transforming logarithmic and exponential functions. Vertical and Horizontal Shifts. Suppose c > 0. To obtain the graph of: y = f(x) + c: shift the graph of y= f(x) up by c units. y = f(x) - c: shift the graph of y= f(x) down by c units. y = f(x - c): shift the graph of y= f(x) to the right by c units

Exponential Equations (from graphs and tables) 1. Arnold dropped a ball during the bouncing ball activity and recorded its height in a table. Part of his table is shown at right. What was the rebound ratio of his ball? From what height did he drop the ball? Write an equation that represents his data. Evidence:

An exponential equation is an equation in which the variable appears in an exponent. A logarithmic equation is an equation that involves the logarithm of an expression containing a variable. To solve exponential equations, first see whether you can write both sides of the equation as powers of the same number. If you cannot, take the common logarithm of both sides of the equation and then ...

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.

When you have multiple factors inside parentheses raised to a power, you raise every single term to that power. For instance, (4x 3 y 5) 2 isn’t 4x 3 y 10; it’s 16x 6 y 10.. When graphing an exponential function, remember that the graph of an exponential function whose base number is greater than 1 always increases (or rises) as it moves to the right; as the graph moves to the left, it ...

Writing Transformations of Graphs of Functions Writing a Transformed Exponential Function Let the graph of g be a refl ection in the x-axis followed by a translation 4 units right of the graph of f (x) = 2x. Write a rule for g. SOLUTION Step 1 First write a function h that represents the refl ection of f. h(x) = −f (x) Multiply the output by ...
