Graph 1:
(-infinity, 2) U [3, infinity)
Graph 2:
{-8, -2} U (3, 8]
Graph 3:
(-infinity, 3) U (3, infinity)
Graph 4:
(-8, -2) or {3}
Graph 5:
(-8, -2) U (-2, infinity)
Hope this helps!
Answer:
If two variables are directly proportional, it means that an increase in the value of one variable would cause a corresponding increase in the other variable. If they are inversely proportional, an increase in the value of one variable would cause a corresponding decrease in the other variable.
Looking at the given values, as x is increasing, y is also increasing. The constant of proportionality is
9/3 = 27/9 = 3
Therefore, the relationship is a direct variation and the function to model it is
y = 3x
