There are two ways you can figure this out.
1: 7.95-3.2-1.05= 3.7
2: 3.2+1.05+(All the choices)=7.95
So you do that till the one of the choices equal 7.95.
So overall, it is D. 3.70
Answer:
This is a many-to-one function as the value of y = -1 corresponds to two values of x:
![\begin{array}{|c|c|}\cline{1-2} x & y\\\cline{1-2} -3 & -1\\\cline{1-2} 0 & 0\\\cline{1-2} -2 & -1\\\cline{1-2} 8 & 1\\\cline{1-2}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7B%7Cc%7Cc%7C%7D%5Ccline%7B1-2%7D%20x%20%26%20y%5C%5C%5Ccline%7B1-2%7D%20-3%20%26%20-1%5C%5C%5Ccline%7B1-2%7D%200%20%26%200%5C%5C%5Ccline%7B1-2%7D%20-2%20%26%20-1%5C%5C%5Ccline%7B1-2%7D%208%20%26%201%5C%5C%5Ccline%7B1-2%7D%5Cend%7Barray%7D)
Step-by-step explanation:
<u>Function</u>
A special relationship where each input (x-value) has a single output (y-value).
A function is <u>one-to-one</u> if each value in the range (y-values) corresponds to exactly one value in the domain (x-values).
A function is <u>many-to-one</u> if some values in the range (y-values) correspond to more than one (many) value in the domain (x-values).
This is a many-to-one function as the value of y = -1 corresponds to two values of x:
![\begin{array}{|c|c|}\cline{1-2} x & y\\\cline{1-2} -3 & -1\\\cline{1-2} 0 & 0\\\cline{1-2} -2 & -1\\\cline{1-2} 8 & 1\\\cline{1-2}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7B%7Cc%7Cc%7C%7D%5Ccline%7B1-2%7D%20x%20%26%20y%5C%5C%5Ccline%7B1-2%7D%20-3%20%26%20-1%5C%5C%5Ccline%7B1-2%7D%200%20%26%200%5C%5C%5Ccline%7B1-2%7D%20-2%20%26%20-1%5C%5C%5Ccline%7B1-2%7D%208%20%26%201%5C%5C%5Ccline%7B1-2%7D%5Cend%7Barray%7D)
This is not a function as the value of x = -5 corresponds to two values of y:
![\begin{array}{|c|c|}\cline{1-2} x & y\\\cline{1-2} -5 & -5\\\cline{1-2} 0 & 0\\\cline{1-2} -5 & 5\\\cline{1-2} 6 & -6\\\cline{1-2}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7B%7Cc%7Cc%7C%7D%5Ccline%7B1-2%7D%20x%20%26%20y%5C%5C%5Ccline%7B1-2%7D%20-5%20%26%20-5%5C%5C%5Ccline%7B1-2%7D%200%20%26%200%5C%5C%5Ccline%7B1-2%7D%20-5%20%26%205%5C%5C%5Ccline%7B1-2%7D%206%20%26%20-6%5C%5C%5Ccline%7B1-2%7D%5Cend%7Barray%7D)
This is not a function as the value of x = -2 corresponds to two values of y:
![\begin{array}{|c|c|}\cline{1-2} x & y\\\cline{1-2} -4 & 8\\\cline{1-2} -2 & 2\\\cline{1-2} -2 & 4\\\cline{1-2} 0 & 2\\\cline{1-2}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7B%7Cc%7Cc%7C%7D%5Ccline%7B1-2%7D%20x%20%26%20y%5C%5C%5Ccline%7B1-2%7D%20-4%20%26%208%5C%5C%5Ccline%7B1-2%7D%20-2%20%26%202%5C%5C%5Ccline%7B1-2%7D%20-2%20%26%204%5C%5C%5Ccline%7B1-2%7D%200%20%26%202%5C%5C%5Ccline%7B1-2%7D%5Cend%7Barray%7D)
This is not a function as the value of x = -4 corresponds to two values of y:
![\begin{array}{|c|c|}\cline{1-2} x & y\\\cline{1-2} -4 & 2\\\cline{1-2} 3 & 5\\\cline{1-2} 1 & 3\\\cline{1-2} -4 & 0\\\cline{1-2}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7B%7Cc%7Cc%7C%7D%5Ccline%7B1-2%7D%20x%20%26%20y%5C%5C%5Ccline%7B1-2%7D%20-4%20%26%202%5C%5C%5Ccline%7B1-2%7D%203%20%26%205%5C%5C%5Ccline%7B1-2%7D%201%20%26%203%5C%5C%5Ccline%7B1-2%7D%20-4%20%26%200%5C%5C%5Ccline%7B1-2%7D%5Cend%7Barray%7D)
Maybe the right two because they are more equal to each other making a better estimate.
The correct answer is parallel
