Let D be the domain of the real valued function `f` defined by ` f(x)=sqrt(25-x^(2))` . Then, write D.

Text Solution

Verified by Experts

The correct Answer is:
N/a
Given function is, `f(x)= sqrt(25-x^(2))`
For real valued of `f(x) " " 25-x^(2) ge 0`
`x^(2) le 25`
`-5 ge 25`
`-5 le x le +5`
`D=[-5,5]`
