    g (x) = 2x + 13

    Step-by-step explanation:

    To shift a function f (x) to the left, we add the unit h inside the function argument.

    That is g (x) = f (x + h)

    To shift a function f (x) to the right, we subtract the unit h inside the function argument.

    That is g (x) = f (x - h)

    Now, to shift f (x) = 2x - 1 to the left, we add the unit 7 inside the function f (x + 7) to have

    g (x) = 2 (x + 7) - 1

    = 2x + 14 - 1

    = 2x + 13
