If 0<b<1,0<b<1, the function decays at a rate proportional to its size. Let’s look at the function f(x)=2xf(x)=2x from our example. We will create a table to determine the corresponding outputs over an interval
To graph an exponential function y = f(x), create a table of values by taking some random numbers for x (usually we take -2, -1, 0, 1, and 2), and substitute each of them in the function to find the corresponding y values. Then plot the points from the table and join them by...
Notice from the table thatthe output values are positive for all values of x; as x increases, the output values grow smaller, approaching zero; and as x decreases, the output values grow without bound.The graph shows the exponential decay function, g(x)=(12)xg(x)=(12)x....
For example, we will take our exponential function from above, f(x) = bx, and use it to find table values for f(x) = 3x. Step One: Create a table for x and f(x) x f(x) Step Two: Choose values for x. x f(x) -2 -1 0 1 2 Step Three: Evaluate the function fo...
The table at the right shows values from an exponential function. Find the values ofaandb, and express an equation that may be represented by this table. With use of the graphing calculator, the difficulty level will be lowered toMODERATE. ...
by considering the special case ofmandnbeing integers, we will try and look at this in terms of the graph of the functionax.As an example, lets takea=2.What happens if we multiply each point on the graph by two? This would amount to a vertical stretching of the graph, moving each ...
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...
