Question
Question: If f(g(x)) = \|sinx\|and g(f(x)) = sin<sup>2</sup>\(\sqrt{x}\)then...
If f(g(x)) = |sinx|and g(f(x)) = sin2xthen
A
f(x) = x, g(x) = sin2x
B
f(x) = sinx, g(x) = x2
C
f(x) = sinx, g(x) = x2
D
f(x) = |x|, g(x) = sin2x
Answer
f(x) = x, g(x) = sin2x
Explanation
Solution
Clearly f(x) = , g(x) = sin2x satisfies both conditions.
