Answer:
B
Explanation:
First off, let's make a table for y = sin(x)
(x , y): (0 , 0) (π/2 , 1) (π , 0) (3π/2 , -1) (2π , 0)
Now, making our table for y = 4sin(x) is simple. We just have to multiply all the y-values from the previous table by 4.
(x , y): (0 , 0) (π/2 , 4) (π , 0) (3π/2 , -4) (2π , 0)
Plotting these coordinates, we get the graph depicted in letter B.
