Answer:
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
