Describe the effect that the transformations $y = 0.5 \cdot f(x - 7) + 8$ have on the graph of $y = f(x)$. Your numerical answers should all be positive. help (numbers)

First take the graph of $y = f(x)$ and perform a horizontal shift ? right left by units.
Next apply a vertical ? stretch compression by a factor of .
Finally perform a vertical shift ? up down by units.
