Answer:
The third and the forth
Step-by-step explanation:
Functions do not have repetition in the x column.
Since the other options have doubles of an x value
(or, to phrase it differently, two y values for one x value)
they are not functions.
Answer:
"simplify" it
Step-by-step explanation:
To convert from vertex form to standard form for a quadratic, eliminate parentheses and collect terms. In short, "simplify" it.
Your final answer for this question is -3(y-2)/2. Hope this helps.
You can find the numerical part of the answer because it is the same on the right side.
For example:
¹ <<==== Regrouped
89
+
67
---------
146 <<=== I had to press space so I could position it.
So that also happens in subtraction, the left side can be found by doing the same steps in the right column.
For example:
67
- <<=== this time there was no regrouping
12
-------
55
