Question

sketch the curve y= (x-1)²/x²+1​

Answer 1

Answer:

first calculate 0 value of curve that is curve will be 0 at x=1 ( assuming the question is (x-1)^2/(x^2 +1).

then calculate continuity of curve , because we need to know weather the curve is continuous around 0 or not.

then calculate minima and maxima (if curve is continuous).

the taking those points curve can be made.

or another approach will be calculate poles and zeros . draw a system stability graph and that will be your answer.
