Determine which sequences of transformations could be applied to the parent function f(x) = x to obtain the graph of g. Shift left 2 units, reflect over x-axis, and then vertically stretch by a factor of 3.

Reflect over the y-axis, vertically stretch by a factor of 3, and then shift up 6 units.

Shift right 2 units, reflect over x-axis, and then vertically stretch by a factor of 3.

Reflect over the x-axis, vertically stretch by a factor of 3, and then shift up 6 units.

Shift right 6 units, reflect over x-axis, and then vertically stretch by a factor of 3.

Shift up 6 units, reflect over the x-axis, and then vertically stretch by a factor of 3.
