C. Is the answer to this question
Answer:
C
Step-by-step explanation:
You can look them up in the graphs.
f(2) means "where is the blue graph when x=2?", and you can see it is at y=0.
No this is not a function because 4 is used twice on the y side
<span>length = L
</span>width = w
L = (5w-2) cm

width = 2 cm
length = 5w-2 = 5*2-2 = 8 cm
