If f(x) = |x| and g(x) = [x], then value of fog(-1/3) + gof(-1/3) is
where, |x| is the absolute function, and [x] represents the greatest integer less than or equal to x.
Explanation:
∵ fog(-1/3) = f[g(-1/3)] = f(-1) = 1
and gof(-1/3) = g[f(-1/3)] = g(1/3) = [1/3] = 0
∴ Required value = 1 + 0 = 1
Hence, option (b).
