Answer:
x-ints: (2,0) & (4,0)
y-int: (0,-8)
vertex: (3,1) *highest point of the graph
line of symmetry: x = 3 *x-value in the middle of x-ints
a value is -# *if parabola points done it's negative, if it points up it's positive

Step-by-step explanation:

Answer:
50 feet
Step-by-step explanation:
Perimeter is the sum of all of the lengths of the sides.
