Define the function h(t) on R as follows: h(t) = 1 if t is in [0, 1/2], -1 if t is in (1/2, 1), and 0 otherwise. Similarly, define the function g(t) on R as follows: g(t) = 1 if t is in [0, 1] and 0 otherwise. Given integers m and n, what is the definition of the function h_(m,n)(t)?

A) h_(m,n)(t) = 2^(m/n)
B) h_(m,n)(t) = 2^((m/n)t)
C) h_(m,n)(t) = 2^(m/n)t
D) h_(m,n)(t) = 2^((m/n)t2)
