If `f9x)=a x^7+b x^3+c x-5,a , b , c`are real constants, and `f(-7)=7, – InterviewSolution

1.	If `f9x)=a x^7+b x^3+c x-5,a , b , c`are real constants, and `f(-7)=7,`then the range of `f(7)+17cosxi s``[-34 ,0]`(b) `[0, 34]``[-34 ,34]`(d) none of theseA. [-34, 0]B. [0, 34]C. [-34, 34]D. None of these
Answer» Correct Answer - A `f(7)+f(-7)= -10` `or f(7)= -17` `or f(7)+17 cosx= -17 +17 cosx` which has range `[-34,0]`.
