Answer:
maximum
Step-by-step explanation:
maximum/vertex is (5,3)
line of symmetry is 5
crosses y axis at (o,-72)
crosses x axis at (4,0) and (6,0)
this the is the equation if you simplify it
-3x^2+30x-72

Answer:
8
Step-by-step explanation:
The distance formula is used to find the distances to each of the points:
d = √((x2-x1)² +(y2-y1)²)
d = √((4-0)² +(2-0)²) +√((4-8)² +(2-(-1))²) +√((4-5)² +(2-4)²)
d = √20 +√25 +√5 = 2√5 +5 +√5
d = 5 +3√5
Comparing to the form ...
d = m +n√5
we see that m=5, n=3. The the sum m+n = 5+3 = 8.
