Sagot :

Answer:

Step-by-step explanation:

They want to use a sin function....

so

sin (x)    goes from -1 to 3   so amplitude is 2

2 sin (x)

it is shifted UP from usual 0 midline to midline 1

2 sin (x) + 1

  and finally, it is compressed from usual period of 2pi to pi

         2pi / pi  = 2

2 sin (2x) +1         That's it !
