Where does the graph of y=sin x from x=0 to x=2pie start. a- at its minimum b- at an x intercept c- at its maximum d- between an x intercept and its maximum

Where does the graph of y=sin x from x=0 to x=2pie start. 
A- at its minimum
B- at an x intercept
C- at its maximum
D- between an x intercept and its maximum

The correct answer is;
A- at its minimum

When a function is graphed. it usually start at its minimum. Considering the plot for the sine function, the Sine Function has this beautiful up-down curve (which repeats every 2π radians, or 360°).

It starts at 0, heads up to 1 by π/2 radians (90°) and then heads down to -1.
