Question

If f(x) = ax7 + bx3 + cx – 5 ; a, b, c are real constants and f(–7) = 7 then maximum value of 1 3 |f(7) + 17 cos x| is

Answer 1

Step-by-step explanation:

Answer:

-17

Step-by-step explanation:

f(-7) = -a(7)^7 - b(7)^3 - 7c - 5 = 7

f(7) = a(7)^7 + b(7)^3 + 7c - 5 = t

Adding both the equations,

t + 7 = -5 -5

t = -17

Hence, f(7) = -17
