Answer:
vertex
Step-by-step explanation:
vertex
If the coefficient a > 0, then the parabola opens upward and the vertex is the lowest point on the parabola. We say that k is the minimum value of the quadratic function. On the other hand, if the coefficient a < 0, then the parabola opens downward and the vertex is the highest point on the parabola.

Answer:
75 ≤ length < 85
Step-by-step explanation:
You know a number 5 or greater will round up to the next higher number in the number place to its left. Similarly, numbers less than 5 round down (get replaced by zero).
This means that 75 will round up to 80. and 84.9999... will round down to 80.
a) The lower bound on length is 75. The length must be at least 75.
b) The upper bound on length is 85. The length must be less than 85.
