In general, the domain is the set of all x-values for the graph.
The issue here is that this isn't the graph of a function. A function has at most one y-value for each x-value and this graph has an infinite number of y-values for the single x-value of 1.
So, either your teacher is wanting you to say the domain is {1}, because that's the only x-value used by the graph, or they're wanting you to say this is a trick question, because this isn't the graph of a function.
The range is the set of all y-values, which is -9<y<9, but again, do they intend this to be a trick question?
Answer:
c = 6
Step-by-step explanation:
Step 1: Write equation
2(5c + 2) - 2c = 3(2c + 3) + 7
Step 2: Solve for <em>c</em>
- Distribute: 10c + 4 - 2c = 6c + 9 + 7
- Combine like terms: 8c + 4 = 6c + 16
- Subtract 6c on both sides: 2c + 4 = 16
- Subtract 4 on both sides: 2c = 12
- Divide both sides by 2: c = 6
