A flatbed trailer carrying a load can have a maximum total height of 13 feet, 6 inches. The photograph shows the height of
the trailer before a load is placed on top. What are the possible
heights of loads that could be carried on the trailer?
What type of model could represent this situation? Explain.

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x

the correct answer is b.

this is because an open circle means < or > & since the line goes left it is < -3.

the next one has a filled circle so it can only be ≥ or ≤ and since the line goes right from 1 it is ≥ 1

hope that
