In this lesson, you have seen how different parameters change the graphs of exponential and logarithmic functions. Below are two equations that are written as general formulas for exponential and logarithmic functions.

Interactive exercise. Assistance may be required. Drag and drop the descriptions below into the box next to the correct parameter.

Think about what you have learned in this lesson. You can apply use of parameters to change graphs of functions to other functions besides exponential and logarithmic functions.

If you saw the equations of two functions f(x) = tanx and g(x) = 2tan(x – 1) + 4, how would you describe the changes made to the graph of f(x) to create the graph of g(x)?

The graph of f(x) would have to be stretched by a factor of 2, moved to the right 1 unit, and moved up 4 units to create the graph of g(x). Close Pop Up
