Answer:
Answer C is the correct answer.
Explanation:
1. Find the y-intercept of both functions.
a) For f(x):
For this function, we can make "x"=0, because the x value is always 0 on the y-intercept.

Therefore, the y-intercept is located at point (0, -6).
b) For g(x):
Looking at the graph, you can tell that the y-intercept is located at point (0, -1).
2. Find the distance between the y-intercepts.
Since the y-intercept have the same "x" value, the absolute difference between the "y" values will give us the distance between the points:

3. Final answer.
The distance between the two y-intercepts is 5, therefore, answer C is the correct answer.
