No. Each input has only one output.
No. The input 1.2 has 2 outputs.
Answers
Answer:
No. The input 1.2 has 2 outputs.
Step-by-step explanation:
See attachment for complete question
The first circle represents the domain while the second represents the range of the function.
For a mapping to be a function, it must either be a one to one relationship or a many to one relationship.
One to one, in the sense that; there can be only one entry in the domain points to one entry in the range of the function.
Many to one, in the sense that: there can be multiple domain entries that point to one entry in the range of the function
However, from the attachment it can be seen that an entry in the domain (1.2) points to two entries in the range (6 and 8).
Hence, this does not represent a function.

Midpoint of (-6, 3) and (8, -7)
Answers
Answer:
Midpoint of (-6, 3) and (8, -7) is: (1, -2)
Step-by-step explanation:
Given the points
(-6, 3)(8, -7)Computing the midpoint of (-6, 3) and (8, -7) using the formula
⇒ [tex]\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-6,\:3\right),\:\left(x_2,\:y_2\right)=\left(8,\:-7\right)[/tex]
⇒ [tex]\left(\frac{8-6}{2},\:\frac{-7+3}{2}\right)[/tex]
⇒ [tex]\left(1,\:-2\right)[/tex]
Therefore, Midpoint of (-6, 3) and (8, -7) is: (1, -2)

Caitlin has a $10 gift certificate to the music store. She has chosen a number of CDs from the $7 bargain bin. If the cost of the CDs is $32 after the gift certificate is credited, which equation could be used to determine how many CDs did Caitlin buy?
Answers
Answer:
32+10=7x
Step-by-step explanation:
Let's solve this first. 32$ is the final price, and then add 10$ because of the gift card, leaving you with 42$. Divide the 42 by 7, because each CD is 7 dollars. The result is 6. So put that into an equation.
32+10=42=7x
x=6!

o (2,1)
o (1,1)
o (2,2)
Answers
Answer:
the ordered pair will be (1, 2)
Step-by-step explanation:
first of all substitute the x and y values into the equation in other to make the equation true.
Therefore y=4x-7
1 = 4(2) -7
1 = 8 -7
1 = 1
Making the first equation true. then move to the second equation which is y = - x + 3
1 = -(2) + 3
1 = 1
