(Choose an alternative)

Choose the expression that describes the inputs (the first coordinates) and the outputs (the second coordinates) of the midpoints (inflections) of the graph of f(x)=2sen(x).

Select one:

to. Output y=1; Inputs x=k2, where k represents integers

b. Output y=0; Inputs x=k2, where k represents integers

c. Output y=1; Inputs x=k2, where k represents integers

d. Output y=1; Inputs x=k, where k represents integers

and. Output y=2; Inputs x=k, where k represents integers

f. Output y=1; Inputs x=k, where k represents integers

g. Output y=2; Inputs x=k, where k represents integers

h. Output y=2; Inputs x=k2, where k represents integers

i. Output y=2; Inputs x=k2, where k represents integers

j. Output y=0; Inputs x=k, where k represents integers
