Question 373003: (0,1)(1,0.5)(2,0.25)(3,0.125)(4,0.0625)what is the rule for this function and can you please show how you got the answer Answer by robertb(5830) (Show Source): You can put this solution on YOUR website! x= 4, f(4) = 0.0625,
x =3, f(3) = 0.125,
x = 2, f(2) = 0.25,
x = 1, f(1) = 0.5,
x = 0, f(0) = 1.
Notice that . Hence *...**...*, the product having x factors. The left most expression gives way to a chain-reaction of cancellations, giving . But f(0) = 1, thus .
And that my STUDENT, is how it's done....
