A non-linear device has the output input relation y = f(x) = x2 (x squared). Assuming the operating point is x0 = 1.5, the linear approximation for small changes would be given by:(adsbygoogle = window.adsbygoogle || []).push({});

(a) y = 1.5x

(b) y = x2 (x squared)

(c) y = 3x

(d) y = 3.5x

(e) none of the above

Can anyone tell me the answer? I was thinking it could be y = x squared?
