Answer:
Option D. 
Step-by-step explanation:
using a graphing tool
Graph and determine the vertex in each case
we know that
If the equation has a maximum value at x=-2, then the x-coordinate of the vertex must be equal to -2 and the parabola open downward
case A) 
The vertex is the point 
case B) 
The vertex is the point 
case C) 
The vertex is the point 
case D)
The vertex is the point 
-------> is the answer

Answer:
A reflection and a dialation
Step-by-step explanation:
- Reflection is when you flip a figure over a line.
- Rotation is when you rotate a figure a certain degree around a point.
- Dilation is when you enlarge or reduce a figure.
In this case a rotation is not nessasary, so I would suggest a reflection in the y-axis and a dialation to shrink the triangle to A'B'C'
So for the transformations that could have occurred to map ABC to A'B'C' you should choose the answer
a reflection and a dialation
