Triangle ABC has points at A(2, 0), B(−1, 3), and C(4, 5). After undergoing a transformation, its new points are A'(6, 0), B'(3, 3), and C'(8, 5). Is the new figure congruent to the old figure? Why or why not?

If you make it a little more clear i can answer it

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.

You should use a calculator for this.
