As below.

Explanation:

color(crimson)(y = A sin (Bx - C) + D

"Given " y = -0.1 sin ((pi/10) x + pi)

"Amplitude " = |A| = 0.1

"Period " = (2pi) / |B| = (2pi) / (pi/10) = 20

"Phase Shift " = -C / B = -pi / (pi/10) = -10, " 10 to the left"

"Vertical Shift " = D = 0

graph{-0.1 sin((pi/10)x + pi) [-10, 10, -5, 5]}
