another one where I need points to graph please. f(x)=(7/5)^(3-x).
I don't see why you can't do this yourself.
f(0) = (1.4)^3 = 2.744
f(1) = (1.4)^2 = 1.960
f(2) = 1.400
f(3) = (1.4)^0 = 1.000
f(4) = (1.4)^-1 = 1/1.4 = 0.7143
You can use Google to quickly do math calculations in you don't have a pocket calculator.

Forget trying to type in the above link. You go there automatically if you go to Google.com and type in
1.4^-2=
That will give you f(5)
drwls,
I should have told you that I do the work myself and with your answers, I confirm what I've done or prove I know nothing--Thanks for your time.
To graph the function f(x) = (7/5)^(3-x), we can follow these steps:
Step 1: Choose a range of values for x.
To start, let's choose a range of x-values to plot on the graph. A good idea is to select values that will allow us to see the overall behavior of the function. Let's choose values for x ranging from -5 to 5.
Step 2: Calculate the corresponding y-values.
For each selected x-value, we need to calculate the corresponding y-value. To do this, plug in the x-values into the given function f(x) = (7/5)^(3-x) and perform the calculations.
For example, when x = -5:
f(-5) = (7/5)^(3-(-5)) = (7/5)^8 = 81.487
Repeat this process for the chosen x-values.
Step 3: Plot the points on a graph.
Now that you have the corresponding coordinates (x, y) for each chosen x-value, plot these points on a graph. Each point will represent a pair of (x, y) coordinates.
Step 4: Connect the points.
Once you have plotted all the points, connect them using a smooth curve. The shape of the curve will give you the graph of the function.
Step 5: Label the graph.
To complete the graph, label the x- and y-axes and add any necessary scale markings or labels.
Remember that for higher accuracy, you can choose more x-values and calculate their corresponding y-values. Additionally, you can use graphing software or online graphing calculators to plot the graph if you prefer a more precise representation.
