How do we obtain the graph of y = 2sin(x) from the graph of y = sin(x)?

How do we obtain the graph of y = ½sin(x) from the graph of y = sin(x)?

The equation y = a ⋅ sin(x) can be seen as replacing the variable y in the equation y = sin(x) by the variable _____.

If f(x) is either sin(x) or cos(x), then changing the value of a in the equation y = a ⋅ f(x) changes the _____________ of the curve.
