Complete the following to analyze the graph shown.
The graph follows the pattern for the sine function: (A. max-zero-min-zero-max) (B. zero-max-zero-min-zero) (C. zero-min-zero-max-zero) (D. min-zero-max-zero-min), starting at the origin. So, a is (A. positive) (B. negative) (C. zero). The maximum value is ___ and the minimum value is ___. So, the amplitude of the function, |a|, is ___. The vertical translation is k = ___.
