Use the knowledge of x- and y- intercepts to choose the correct graph of the equation 3x+6y=6

Graph g(x)=2cosx . use 3.14 for π . use the sine tool to graph the function. graph the function by plotting two points. the first point must be on the midline and closest to the origin. the second point must be a maximum or minimum value on the graph closest to the first point.

What is the value of x in the this question ?
