The exponential function, f(x)=2^x, under goes two transformations to g(x)=1/3•2^x-7. how does the graph change select all that apply

Step-by-step explanation:

TRANSFORMATIONS:

Vertical shifts:      Shifts up/down n units

Horizontal shifts:    Shifts left/right n units

Reflection:  Reflection over x-axis

Reflection:  Reflection over y-axis

Dilation:

Dilation of x-coordinate n > 1 graph narrows; n < 1 graph widens

Dilation:

Dilation of y-coordinate n > 1 graph narrows; n < 1 graph widens.

=============================================================

We have:

Dilation of y-coordinate (graph widens) and Shifts right 7 units.

look at the picture.

the solution is 12x-6y
