Let `f(x)={(x^4-5x^2+4)/(|(x-1)(x-2)|)\ \ \ \ ,\ \ \ x!=1,\ 1 6\ \ \ \ \ \ \ \ \ \ \ \ \ ,\ \ \ x=1 ,\ \ \ \ \12 ,\ \ \ \ \ \ \ \ \ x=2` . Then, `f(x)` is continuous on the set `R` (b) `R-{1}` (c) `R-{2}` (d) `R-{1,\ 2}`

Explanation

For any `x ≠ 1, 2`, we find that
f(x) is the quotient of two polynomials and a polynomial is everywhere continuous.
Therefore, f(x) is continuous for all `x ≠ 1, 2.`
