Answer:
Translation 1 unit up
Explanation:
The graph of f(x)=2x+3 and g(x)=2x+4 represent straight lines .
The slope of both lines are 2.So the two lines are parallel.Line f(x) will have y intercept 3 and line g(x) will have y intercept 4.
line f(x) is translated 1 unit up to get line g(x)=2x+4.
Option 3 is the right answer that is translation 1 unit up
