Example 2: Evaluating Exponential Functions Let f(x)=5(3)x+1.f(x)=5(3)x+1. Evaluate f(2)f(2) without using a calculator. Show Solution Try it #2 Let f(x)=8(1.2)x−5.f(x)=8(1.2)x−5. Evaluate f(3)f(3) using a
We can understand the process ofgraphingexponential function by taking some examples. Let us graph two functions f(x) = 2xand g(x) = (1/2)x. To graph each of these functions, we will construct a table of values with some random values of x, plot the points on the graph, connect t...

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 ...
Constructing functions from a table of values may be a very simple process, or it may be a more challenging process, depending upon the information provided in the table. Before we start, we shouldcheck to see if the table CAN BE represented by an exponential function. Remember that exponenti...

Graphs of Log Functions Logarithmic Functions Example – pg. 323 Graph the function, not by plotting points or using a graphing calculator, but by starting from the graph of a log a x function. State the domain, range, and asymptote Logarithmic Functions ...
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...
The algorithms allow the computation of elementary functions such as the logarithm, exponential function, sine, cosine and their inverses with only shifts, adds, comparisons and table lookups.Some early oating-point units (FPUs) used CORDIC algorithms and your pocket calculator surely does....
