The function that represents the given trigonometric graph is; f(x) = cos (x)
How to Interpret Trigonometric Graphs?
From the given trigonometric Graph, we can see the following;
When x = 0, y = 1
When x = π/2, y = 0
When x = π, y = -1
When x = 2π, y = 1
Now, according to trigonometric functions in radians, we know that;
cos 0 = 1
cos π/2 = 0
cos π = -1
cos 2π = 1
These values correspond with what we have in the given trigonometric graph and as such we can say that the function that is graphed is;
f(x) = cos (x)
