A table (relation) may or may not represent a function
The table that represents a function is Hal's table
<h3><u>Tables and relations</u></h3>For a table to represent a function, then the input values must point to exactly one output value.
This means that:
Each height entry must correspond to exactly one age entry
From the given tables (see attachment), we can conclude that
Hal's table represents a function
This is so because, the age entries on this table has one corresponding one height entry

Answer:
One rose bush = $3
One bunch of ornamental grass = $4
Step-by-step explanation:
We can set up a system of equations to solve for this. Let cost of 1 rose bush be r and cost of 1 ornamental grass be g. Thus we can form 2 equations:
We can multiply the first equation by -2 so that we can eliminate g. Thus, we have:
Thus, 1 rose bush is $3. Now plugging in r = 3 into the first original equation, we can solve for g:
Thus, 1 bunch of ornamental grass is $4.
