Question

Graph g(x)=4cosx .

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.

Answer 1

Answer: The graph of g(x) = 4cosx is a horizontal dilation of the graph of y = cosx by a factor of 4.

To graph the function, we can use the following two points:

(0, 4) which is the point on the midline closest to the origin

(3.14/2, 0) which is the maximum point closest to the first point

We can then use these points to plot the graph of g(x) = 4cosx using the sine tool. It will be horizontal shifted of the graph of y = cos(x) by a factor of 4.
