Given the function f(x) = 3^(x+1) −4, describe the transformations that will occur to graph f^−1 (x).

options:
a) the graph of the inverse function will reflect over the line y=x, vertically shift 1 unit up and horizontally shift 4 units to the right.

b) the graph of the inverse function will reflect over the line y=x, vertically shift 1 unit down and horizontally shift 4 units to the left.

c) the graph of the inverse function will reflect over the line y=x, vertically shift 4 unit up and horizontally shift 1 unit to the right.

d) the graph of the inverse function will reflect over the line y=x, vertically shift 4 unit up and horizontally shift 1 unit to the left.
