Question

Functions f(x) and g(x) are shown below:


f(x) g(x)
f(x) = 2cos(x) graph of sine function which starts at 0 comma 0 and decreases to the minimum of pi over 2 then increases to the maximum 3 pi over 2 then decreases to 2pi where the cycle repeats



Using complete sentences, explain how to find the maximum value for each function and determine which function has the largest maximum y-value.
