What is the period of the function f(x) shown in the graph? A sinusoid function graphed on a coordinate plane. The horizontal x-axis ranges from negative 5 pi over 4 to 5 pi over 4 in increments of pi over 4. The vertical y-axis ranges from negative 1 to 8 in increments of 0.5. The function begins at begin ordered pair negative 5 pi over 4 comma 1 end ordered pair and increases in increments of pi over 4 until reaching begin ordered pair 5 pi over 4 comma 7 end ordered pair. The function begins at begin ordered pair negative 5 pi over 4 comma 1 end ordered pair and increases to a maximum value of begin ordered pair negative 3 pi over 4 comma 7 end ordered pair. The graph then decreases to a minimum value of begin ordered pair negative pi over 4 comma 1 end ordered pair and increases to a maximum value of begin ordered pair pi over 4 comma 7 end ordered pair. The graph then decreases to a minimum value of begin ordered pair 3 pi over 4 comma 1 end ordered pair and increases to a maximum value of begin ordered pair 5 pi over 4 comma 7 end ordered pair.
