The graph of f(x) = (0.5)x is replaced by the graph of g(x) = (0.5)x − k. if g(x) is obtained by shifting f(x) down by 7 units, then what is the value of k?

answer:

step-by-step explanation:

there are some transformations for a function f(x). one of these transformations is the following:

if , then the function is shifted down "k" units.

in this case you know that the function   is obtained by shifting the function down by 7 units.

therefore the transformation is:

, where the value of "k" is the following:

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.

is it 35
