The graph of f(x) = 2x + 4 shifts five units to the right when it is replaced with the graph of f(x) = 2x - k. what is the value of k?

a.) -5
b.) -1
c.) 1
d.) 5

C.) 1

Remember the rules for shifting functions:

shifts the function b units upward

shifts the function b units downward

shifts the function b units to the left

shifts the function b units to the right

Since we want tho shift 5 units to the right, we are using the rule: shifts the function b units to the right; in other words, we need to subtract 5 units to the input of the function:

But notice that there is already a negative sign in , so to get , k must be equal to positive 1.

Option C. is the correct

The value of k is 1
