Answer:
The correct option is A.
Step-by-step explanation:
The vertex form of an absolute function is
Where, (h,k) is vertex.
Domain is the set of input values.
The given function is
It is the vertex from of an absolute function. Here h=-4 and k=1, so the vertex of the function is (-4,1).
These functions are defined for all real values of x. So, the domain of the given absolute function is all real numbers
Therefore the correct option is A.
Answer: Yes, it is correct
Step-by-step explanation: Because of that, When you multiply 4.2 x 3 x 4 = 50.4
Answer: 160 + 160 = 320
360 + 360 = 720
720 + 320 = 1040
-4
Slope = y2 - y1/x2 - x1
Given
x1 = 6
y1 = 2
x2 = 4
y2 = 10
Therefore
Slope = 10 - 2/4 - 6
= 8/-2
= -4
