shift f(x)=-3sin(1/2 x-pi/4)+1

shift

f (x) = - 3 sin (\frac{1}{2} x - \frac{π}{4}) + 1

Phase : \frac{π}{2}, Vertical : 1

Solution steps

f (x) = - 3 sin (\frac{1}{2} x - \frac{π}{4}) + 1

g (B x - C) = sin (\frac{1}{2} x - \frac{π}{4}), B = \frac{1}{2}, C = \frac{π}{4}, D = 1

Therefore, the phase shift

\frac{C}{B}

\frac{\frac{π}{4}}{\frac{1}{2}}

\frac{π}{2}

The vertical shift

D
