The parabola opens towards left, this means the squared term is y with negative coefficient.
The vertex is given to be the point (-1,-3). So, the general equation of the parabola will be like:
where a is any constant.
In the given options, only 1 such equation is available and that is option C.
So the answer to this question is option C
Answer:
Here is one idea:
You can use a regression line to predict what will happen at a time not given by your data. You can use it to make predictions about future times.
Here is another one:
The equation for the regression line or even the graph of can tell us if the data is increasing as we move through future times or if it is decreasing as we move through future times.
Try to come up with one of your own so you can have three. :)
100 and -100 are the two solutions for the square root of 10,000
1 is to a because corresponding angles are located in the same location, comparative to each line.
2 is to d because one, they are on the same side of the transversal, and two, they are "facing" each other.
3 is to c because vertical angles are formed opposite to each other when two lines intersect, like shown.
4 is to b because they are on different sides of the transversal, and are "facing" each other.
5 is to e because they are not "facing" each other, and they are on different sides of the transversal.
