Here's another one.
See the attached picture.
It must be ......................,..UH...............,,i don’t know
The correct option has been marked in the Figure below. A function 
from a set 
to a set 
is a relation that assigns to each element 
in the set exactly one element 
in the set . The set is the domain (also called the set of inputs) of the function and the set contains the range (also called the set of outputs).
For our correct option we have:
<u>Set A, Domain:</u>
Inputs: -2, 1, 0, 1, 2, 3
<u>Set B, Range:</u>
Outputs: -1, 0, 1, 2, 3
This is a function because this is a relation that assigns to each element in the set exactly one element in the set . So, the assignation is as follow:
- -2 (in x) matches to 0 (in y)
- -1 (in x) matches to 3 (in y)
- 0 (in x) matches to 2 (in y)
- 1 (in x) matches to -1 (in y)
- 2 (in x) matches to 0 (in y)
- 3 (in x) matches to 2 (in y)
why is no one answering? I also need help in this question!!!!
Answer:
The gradient of the line segment between the two points is -1
Step-by-step explanation:
The gradient of the line segment between two points is also known as the slope,
We can find this by using the formula; y₂ - y₁ / x₂ - x₁
The points given to us are;(-1,2) and (-2,3).
This implies x₁ = -1 , y₁=2 x₂ = -2 y₂= 3
We can now proceed to insert our values into the formula;
Gradient = y₂ - y₁ / x₂ - x₁
= 3 - 2 / -2-(-1)
= 1 / -2 + 1
=1/-1
Gradient = -1
Therefore the gradient of the line segment between the two points is -1
