Question

Used the graph of the function to find the indicated values.

Answer 1

From the graph,

`f((\pi)/(2))=2`

From the graph, the values of x for which f(x) is zero is,

`x=-2\pi,-\pi,0,\pi,2\pi,\ldots.`

The rangge of a function is defined the possible y values of the function.

From the graph, the range is [-2,2].
