Answer: First option.
Step-by-step explanation:
Below are shown some transformations for a function [tex]f(x)[/tex]:
1. If [tex]f(x)+k[/tex], the function is translated "k" units up.
2. If [tex]f(x)-k[/tex], the function is translated "k" units down.
3. If [tex]f(x+k)[/tex], the function is translated "k" units to the left.
4. If [tex]f(x-k)[/tex], the function is translated "k" units to the right.
In this case, you can observe in the graph that the function [tex]f(x)[/tex] intersects the y-axis at:
[tex]y=1[/tex]
And the function [tex]g(x)[/tex] intersects the y-axis at:
[tex]y=5[/tex]
Knowing this, you can idenfity that:
[tex]g(x)=f(x)+4[/tex]
Therefore, you can conclude that the statement that best describes the translation of [tex]f(x)[/tex] to [tex]g(x)[/tex] is: "Translation of four units up".
