Answer
The graph of \( g \) is the same as the graph of \( f \) but shifted 13 units up.
Solution
1. The function \( f(x)=2x+5 \) has a graph that is a straight line with slope \( 2 \) and \( y \)-intercept \( 5 \).
2. The function \( g(x) \) is given by
\[
g(x) = (2x+5)+13.
\]
This can be rewritten as
\[
g(x) = 2x + 5 + 13 = 2x + 18.
\]
3. Since \( g(x) \) has the same slope of \( 2 \) as \( f(x) \), the steepness of the graph does not change.
4. The \( y \)-intercept of \( g(x) \) is \( 18 \) (as opposed to \( 5 \) for \( f(x) \)). This is because each point on the graph of \( f \) has been increased by \( 13 \) in the \( y \)-direction.
5. This represents a vertical shift upward by \( 13 \) units.
Thus, the graph of \( g \) is identical to the graph of \( f \) except that it is shifted \( 13 \) units up.
The answer is E.

The graph of \( g(x) \) can be viewed as a vertical shift of the graph of \( I(x) \). Since \( g(x) = I(x) + 13 \), this means that every point on the graph of \( I(x) \) is moved up by 13 units. So, if you plot \( I(x) \) first, then simply take each point and elevate it by 13 units, you'll get the graph of \( g(x) \). In conclusion, the graph of \( g \) compared to the graph of \( I \) is a simple upward shift. The answer that fits this description is E: The graph shifts 13 units up.
