The exponent, or antilog for short, is the inverse operation of taking the logarithm of a number. It can be calculated using theexponential function. Enter Information Base (x) Power (n) Calculate Results Fill the calculator form and click on Calculate button to get result here ...
In our first example we will evaluate an exponential function without the aid of a calculator.Example Let f(x)=5(3)x+1f(x)=5(3)x+1. Evaluate f(2)f(2) without using a calculator. Show Answer In the following video we present more examples of evaluating an exponential function at ...
To get a sense of the behavior of exponential decay, we can create a table of values for a function of the form f(x)=bxf(x)=bx whose base is between zero and one. We’ll use the function g(x)=(12)x.g(x)=(12)x. Observe how the output values in Table 4 change as the inp...
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 ...
The geometric interpretation of the first "law" of exponents can then be stated as follows: iff(x)is some exponential function, then a stretch of the formkf(x)is equivalent to a translation of the formf(x+c). This is a property that can be observed on a graphing calculator or with ...

Answer to: Complete the table for the exponential function f(x) = 3^x-2 and then graph the function. Also, identify the y-intercept for the...
Replace the values in the formula and solve, most preferably using a calculator: y=a(1−r)xy=35,690(1−0.03)22y=35,690(0.97)22y≈35,690(0.5117)y≈18,261 Harry would have to sell the car for about $18,261 today. Example 2: "The population of a remote island off the east ...
