Answer:
Option d
Step-by-step explanation:
Consider the parent function y =sinx which has amplitude 1 and period 2pi.
Compare this with out graph passing through 3 points given as
(0.5,5) (1.5,-15) and (0,5)
Since maximum value is 5 and min value is -15 amplitude = 1/2 (20) = 10
Also period =2 instead of 2pi.
Hence pi must be coefficient for x
Also the curve does not pass through origin but passes through (0,-5)
So vertical shift of 5 units down.
Hence the curve equation is
[tex]y=10sin \pi x -5[/tex]
