Remember that the formula is f (x) = a (x-h) ^2 + k.

1/2: The closer to zero the a value, the wider, so this will stretch vertically.

5: This means that h=5, so the graph is shifted left 5 units.

7: This means that k=7, so the graph is shifted up 7 units.

The answer is stretched vertically, shifted left 5 units, shifted up 7 units.
