2. A ≤ -3 and a ≥ 3
3. a ≥ -3 or a ≤ 3
4. A ≤ -3 or a ≥ 3
This question is worth 40 points. Please help im struggling with this answer!
Answer:
1. a ≥ -3 and a ≤ 3
I am assuming you mean to have an = sign as well
Step-by-step explanation:
|a| < =3
we get two solutions, one positive and one negative
remember to flip the inequality for the negative
a<=3 and a >= -3
All the answers except C has a Vertical Line when graphed. It must pass the Vertical line test in order to be a function.
Vertical Line Test: If you can draw a vertical line anywhere on a graph so that it hits the graph in more than one spot, then the graph is NOT a function.
C.) can pass the test since it's a horizontal line.
Hope this helps!
