Answer:
A
Step-by-step explanation:
At the vertex, the quadratic term in this notation must be zero, i.e., the (x-1) part. This happens for x=1. So you can already rule out answers C and D.
Now fill in x=-2 in both remaining answers and see what happens.
For A: y = -2(-2 - 1)² + 3 = -15
For B: y = (-2 - 1)² + 3 = 12
That eliminates B and leaves A.
We solve this equation : 4y+6=-2
4 y+ 6=-2
4y=-2-6
4y=-8
y=-8/4
y=-2
Therefore: It has one solution .
Answer:
it is letter d or the last answer
Step-by-step explanation:
i just multiplied the 4 and -3, 3 and 1, -1 and -2, -1 and 2
Domain: 
Range: 
The relation is not a function.
Explanation:
The coordinates
are plotted in the graph. The image of the graph is attached below.
The domain of a relation is the set of all x-values for which the function is well defined. Thus, the domain are 
The range of a relation is the set of all y-values obtained by substituting the values for x in the function. Thus, the range are 
The relation
is not a function since, -4.7 has two different y-values. By definition of function, the function cannot have two different y-values for the same x-value.
