Graphs of Exponential Functions     Math Help     Game Tips: - The relations y=2x, y=3x, and y=4x are examples of exponential functions. - A 'positive constant base raised to a variable exponent' = (constant)(variable) is an 'Exponential function'. - In general, an 'Exponential function' is represented by the formula y=ax where a>0.  [Also a cannot be 1.]    Notice that for integer a>0, the graph of y=ax passes through the point (0,1). - The relations y=3(2x), y=4(6x), and y=2(3x) are examples of exponential functions with a front multiplier. - In general, a 'Constant times an Exponential function' can be represented by a formula such as y=k(ax).    For integer a>0, the graph of y=k(ax) passes through the point (0,k). - In this game, 'k' is an integer from -3 to 3 and 'a' is an integer from 2 to 5. - Notice y=2x has graph points such as (-1,1/2), (0,1), (1,2), and (2,4)... ,    while a relation such as y=2(3x) has graph points such as (-1,2/3), (0,2), (1,6), and (2,18)... . - There are many applications of exponential functions. For example, exponentials are used in formulas    for compound interest, for geometric growth patterns [ax], and for radioactive decay patterns [a-x]. - The game can be played using the mouse by itself or using the keyboard by itself. - If the game doesn't respond to keyboard input, click inside the game area to reset the game's focus. - Adjust the game's speed by pressing the + or - key repeatedly.
