and f(x) is an exponential function in terms of x. Also, note that the base in each exponential function must be a positive number. i.e., in the above functions, b > 0 and e > 0. Also, b should not be equal to 1 (if b = 1, then the function f(x) = bxbecomes f(x) ...

The second format—x1 / n— is what you’ll want to put into a graphing program or calculator. Some calculators do have nth root functions, like the Casio FX-9750G (press SHIFT and ). Examples The graph above shows an nth root function where n = 2. When n = 2, the function is ...
(because you would have a straight line), (2) that thex-coordinates not be the same (you wouldn't have a function) and (3) that they-coordinates of the points be non-zero with the same signs (remember the asymptotic nature of the graphs of these exponential functions - always all ...

Exponential functions 指数函数 We have spent plenty of time so far reasoning about repeated multiplication, and how to generalize this idea. However, some goodvisualintuition would be nice: what does the exponentiation process look like? The easiest base to picture is 2, so we will look at the...
