Question

another one where I need points to graph please. f(x)=(7/5)^(3-x).

Answer 1

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.

Answer 2

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.
