Answer:
The trignometric function that best represents the graph is:
Step-by-step explanation:
It is given that the trignometric function passes through:
(0,-4) , (π/2,0) , (π,4) , (3π/2,0) , (2π,-4) and (5π/2,0) and (3π,4)
We will check these points in each of the given options and see what holds true.
2)
When we put x=0 we obtain:
Hence, option 2 is incorrect.
3)
When we put x=0 we get:
Hence, option 3 is incorrect.
4)
When we put x=0 we obtain:
Hence, option 4 is incorrect.
1)
When we put each of the x-value we see that the y-value also holds.
Hence, option 1 is true.
Also we can see in the graph.
