Let `f(x)=a sin x+c`, where a and c are real numbers and a>0. Then `f(x)lt0, AA x in R` ifA. `c lt -a`B. `c gt -a`C. `-a lt c lt a`D. `c lt a`

Answer» Correct Answer - A
a `sin x + c lt 0, AA x in R`
`rArr sin x lt - (c )/(a)`
`rArr -(c )/(a)gt sin x, AA x in R`
`rArr -(c )/(a)gt 1`
`rArr -c gt a`
`rArr c lt -a`
