The mid-point of the domain of the function `f(x)=sqrt(4-sqrt(2x+5))` for real x is -A. `1//4`B. `3//2`C. `2//3`D. `-2//5`

Answer» Correct Answer - B
`f(x)=sqrt(4-sqrt(2x+5))`
`4-sqrt(2x+5)ge0" "2x+5ge0`
`sqrt(2x+5)le4" "xge-5//2`
`xle(11)/(2)`
`x in[-(5)/(2),(11)/(2)]`
mid point `=(-5//2+11//2)/(2)=(3)/(2)`
