There you go here’s the graph
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:
9
Step-by-step explanation:
The constant is the plain number that doesn't have a letter attached.
Answer:
-6
Step-by-step explanation:
if you use y = mx + b, b is the y-intercept
The answer is C.The area of the triangle in Step 3 should be doubled since there are 2 triangles.
