Answer:
x < -3
Step-by-step explanation:
This is simply an inequality. This should be fairly easy, but since it has a variable, you need to find the domain. Since -6(1) + 3 = -3, we can't do that. So what can we do? What if we use -1 for x instead? We get 9, so still no. We need to determine when the statement starts becoming true. At this point, -3 for x makes the expression equal to 21. This leads us to our answer.
