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

Answer 1

f(x) = 2cos(x)
g(x)=3sin(x+pi)
The range of a function is the set of all the possible dependent values ​​that the relation can produce.

using a graphical tool we can visualize the maximum values ​​of the range of the function

observing the attached graph

for
f(x) = 2cos(x) the maximum value of y is 2
and for
g(x)=3sin(x+pi) he maximum value of y is 3
