Answer
Graph of $y = 3 + \sin (\pi x - \frac{\pi}{2})$ will be
Graph of $y = \sin (\pi x - \frac{\pi}{2})$ (problem 44) shifted 3 units downward
Work Step by Step
We know that,
The graphs of $y = k + \sin x$ and $y = k + \cos x$ will be sine and cosine graphs that
have been translated vertically k units upward if $k > 0$, or k units downward if
$k < 0$,
Using this
Graph of $y = 3 + \sin (\pi x - \frac{\pi}{2})$ will be
Graph of $y = \sin (\pi x - \frac{\pi}{2})$ (problem 44) shifted 3 units downward
