Which of the following functions indicates a shift downward 3 units from the function ƒ(x) = 2x ?

ƒ(x) = 23
ƒ(x) = 2(x+3)
ƒ(x) = 2x−3
None of these choices are correct.
ƒ(x) = 2x − 3

Option C: is the equation that shifts the function 3 units downward.

Explanation:

The given function is

Now, we shall shift the function 3 units downward.

To shift the function downwards, we shall subtract a constant from the outside of the function results the function to shift downwards.

The general form to shift the function downwards is given by

Thus, substituting and in the above expression, we have,

Thus, the equation can be written as

Hence, the equation that shifts the function 3 units downward is

step-by-step explanation:

i am not sure sorry : c

i believe the correct answer is b.
