I will assume that are integers.3. Let
Find a function of the form . .so that:
Specify at what point is defined.
We have: .
Multiply top and bottom by
Since this is to be equal to , we have: .
Equating coefficients: .
Divide (3) by (2): .
Substitute into (1): .
. . Let . . . then
Substitute into (4): .
is defined for all real
