Question

The graph of f(x) = 2x + 3 shifts 10 units to the right when it is replaced with the graph of f(x) = 2x − k. What is the value of k?

A: 3
B: 7
C: 10
D: 13

Answer 1

The Answer Is B, Hope This Helps!

Answer 2

To shift a graph to the right, you subtract the number of units of the shift from x

The original graph is 2x +3, you want to shift right 10 units, so subtract 10 from the +3 ( 3-10 = -7) to get 2x -7

K would be B. 7
