Answer:
Step-by-step explanation:
Remember that the range is the set value that defined the dependent variable of a function, which is represents with Y.
So, all transformations about vertical shifts, it would represent a change to the range set of the exponential fuction.
For example, let's say that we have the function [tex]f(x)=2^{x}[/tex], which domain is all real numbers and which range is all real numbers greater than zero.
Now, let's say we transform that function to [tex]g(x)=2^{x}+6[/tex], which is the same function but shifted up 6 units.
Notice that the function [tex]g(x)[/tex] has the same domain -all real numbers- but different range, because it's defined by all real numbers greater than 6.
Therefore, the transformation that can change the range of a function is B. Vertical Shift.
