Question

How does the graph of the function g(x) = 2x – 3 differ from the graph of f(x) = 2x?

Answer 1

Answer: The graph of function g(x) is shifting down by 3 (vertical shift) because the -3 is not part of x but y (the whole graph). Originally there is no y-intercept and the f(x) function crosses the origin, but now there is a y-intercept at (0, -3)
