Answer:
The graph c.
Step-by-step explanation:
We know from the function f(x) = 5sin(-2t) three things:
1. The amplitude is 5.
2. The period is π.
3. Because of the negative in the argumen, the graph will be reflected over the y-axis (Compared to the graph of sin(x))
Then, evaluating all the functions we find:
1. All of graphs have an amplitude of 5.
2. The graph b has a period of 2π.
3. The graph a is not reflected over the y-axis.
Then, the correct graph is the graph letter C.
