Question
If f(x) = 
, then
, thenOptions
A.
f(x) = 2 sin 2
f(x) = 2 sin 2 B.
f(x) = 2 sin 2
f(x) = 2 sin 2 C.f(x) = 2 cos 2
f(x) = 2 cos 2 D.
f(x) = 2 cos 2
f(x) = 2 cos 2 Solution
Let f(x) = 
(A)
f(x)
for x = - 1 |x| = - x
f(x) =
Now
=
= 2sin2
(B)
=
= 2sin2
(A)
f(x)for x = - 1 |x| = - x
f(x) =
Now
=
= 2sin2(B)
=
= 2sin2Create a free account to view solution
