Answer:
{(a, 1), (b, 1), (c, 1)}, {(1, a), (2, a), (3, a)}, and {(a, a), (b, b), (c, c)}
**All functions are relations, but not ll relations are functions**
In a function, the x values CAN NOT repeat, only y-values can.
Answer:
2
Step-by-step explanation:
Since there are four negative signs, we have -1 multiplying each other 4 times, multiplying by positive 2. This is then 1 * 2, which is 2.

1. From the graph of absolute value function:
a. The domain is 
b. The range is 
c. The graph is increasing for all 
d. The graph is decreasing for all 
2. From the graph of quadratic function:
a. The domain is 
b. The range is ![y\in (-\infty,0]](https://tex.z-dn.net/?f=y%5Cin%20%28-%5Cinfty%2C0%5D)
c. The graph is increasing for all 
d. The graph is decreasing for all 
Answer:
Yes
Step-by-step explanation:
To figure out if (1,2) is a solution to the system, we can plug the values in and see if it is true.
3x-2y=-1
3(1)-2(2)=-1
3-4=-1
-1=-1
It is true for this equation. Now let's check the next one.
y=-x+3
2=-(1)+3
2=2
Since both equations are true when we plug the values in, (1,2) is a solution to the system.
