If `3-((x^2)/(12))lt=f(x)lt=3+((x^3)/9)` for all `x!=0,` then find the value of `("lim")_(xvec0)f(x)`

Text Solution

Verified by Experts

According to question,
`underset(xto0)lim(3-(x^(2))/(12))leunderset(xto0)limf(x)leunderset(xto0)lim(3+(x^(3))/(9))`
or `(3-0)leunderset(xto0)limf(x)le(3+0)`
Hence, `underset(xto0)limf(x)=3" "`(Using sandwich theorem)
