Question

Which graph is correct? No horizontal shift,cosine, amplitude=2 and period of 2pi/3

Answer 1

Answer:

# 1

Step-by-step explanation:

It is number one because if the Period is ( 2pi /3 ) them the middle of the function should be ( pi/3 ) and since the function is a cosine function, the graph should start at the top (2) instead of at 0.

Hope I helped!!

Answer 2

Answer:

cosine, amplitude=2 and period of 2pi/3 is shown in figure 1.

Step-by-step explanation:

COSINE FUNCTON

Cos function (or cosine function) in a triangle is the ratio of the adjacent side to that of the hypotenuse.

cosine α = Adjacent Side/Hypotenuse

Since its amplitude is 2 .  So the value of cosine function at COSIN 0 will be 2 and its period will be 2pi/3.

The above described situation is rightly depicted in figure 1.
