Answer:

As below.

Explanation:

Standard form of equation is #y = a sin(bx - c) + d#

Given : #y = - sin ((pi/4)x + pi/4) + 1#

#"Amplitude " = |a| = 1#

#"Period " = p = (2pi) / |b| = (2pi) / (pi/4) = 8pi#

#"Phase Shift " = -(pi/4) / (pi/4) = 1# #color(white)(aaa)("1 to the left")#

#"Vertical Shift" = d = 1#

graph{-sin((pi/4)x + (pi/4)) + 1 [-10, 10, -5, 5]}
