Answer:
did you add the whole question and i am saying this here because it won't let me comment
Step-by-step explanation:
Answer:
Not a function because there are two values of y for x = -8.
4 3/4 - 2/5
Find a common denominator
4 15/20 - 8/20
Solve
4 7/20
The plank is 4 and 7/20 feet long now.
The functions could represent g(x) is B. 
<h3>How can the function be determined?</h3>
Using the general equation 
The g(x) has intercept of y=-2,
Then the y-intercept of f(x) is at y=3
If we find the difference between both y-intercepts, we have
( -2 -3) = -5
Then b=-5
Hence,
is correct.
