If x represents # tshirts sold, wouldn't it simply be: (0,0) (1, 13.50) (2, 27), etc... am I missing something?
Answer:
The other endpoit has this cordinadetes (11, 11).
Step-by-step explanation:
Midpoint (MD) (Xm, Ym)
Xm = 5
Ym = 2
Xm of the Midpoint: Xm = X1 + X2/ 2
Ym of the Midpoint: Ym = Y1 + Y2/2
<em>We can say that S is (x1, y1), so x1 = -1 and y1 = -7</em>
Then:
Xm = -1 + x2/2
5= -1 + x2/2
10 = -1 + x2
x2 = 11
Also:
Ym = -7 + y2/2
2 = -7 + y2/2
4 = -7 + y2
11 = y2
- Yes, the height, h(t) of a ball t seconds after it's dropped from the third floor of a building is a function.
- No, table B is not a function because no function can have the same y-values (5) for different x-values (1 and 8).
- Yes, table C is a function because it has different y-values for same x-values.
- Yes, graph D is a function because it has different y-values for same x-values.
<h3>What is a function?</h3>
A function can be defined as a mathematical expression which is used to define and represent the relationship that exists between two or more variables.
<h3>The types of function.</h3>
In Mathematics, there are different types of functions and these include the following;
- Piece-wise defined function.
For this exercise, we would indicate whether or not each of the above mathematical relation represents a function:
- Yes, the height, h(t) of a ball t seconds after it's dropped from the third floor of a building is a function.
- No, table B is not a function because no function can have the same y-values (5) for different x-values (1 and 8).
- Yes, table C is a function because it has different y-values for same x-values.
- Yes, graph D is a function because it has different y-values for same x-values.
In conclusion, we can infer and logically deduce that a function maps every x-value in a valid domain to a single y-value only.
