Let `f(x)=a-(x-3)^(8//9)` then greatest value of f(x) is

A

3

B

a

C

no maximum vlaue

D

non of these

Text Solution

Verified by Experts

The correct Answer is:
B
We have
`f(x)=a-(x-3)^(8//9)`
Clearly `(x-3)^(8//9) gt 0 " for all " x in R`
`rArr f (x) le a " for all " x in R `
Hence the reastest value of f(x) is a
