Answer:
The correct option is C.
Step-by-step explanation:
The translation is defined as
Where, a is horizontal shift and b is vertical shift.
If k>0, then the graph shifts b units up and if k<0, then the graph shifts b units down.
In the given graph red line represents the the function g(x) and blue line represents the function f(x).
y-intercept of g(x) = 1
y-intercept of f(x) = -3
It means the graph of f(x) shifts 4 unit up to get the graph of g(x). So, the value of k is 4.
Therefore the correct option is C.

Distance to checkpoint A from starting line = 20 yards.
Then from A to B distance = 12 yards.
Let us take starting point C.
So, it would make a right triangle.
We have AB = 12, AC = 20, we need to find BC, that is Hypotenuse of the right triangle.
According to Pythagoras theorem:
BC = 23.32.
<h3>Therefore, 23.32 yards is the distance from Checkpoint B to the starting line.</h3>
