Hello, tamilmassive!

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): .

Therefore: .

is defined for all real
