Answer:
2) (-∞, 17]
Step-by-step explanation:
The leading coefficient of the function is negative, so the parabola opens downward. The vertex will be a maximum, the upper end of the range. The lower end of the range will be -∞.
The vertex of the function lies on the axis of symmetry. The maximum can be found by evaluating the function at x=-4.
y = -(-4)² -8(-4) +1 = -16 +32 +1 = 17
The range of the function is (-∞, 17].
Answer:
answer is a
Step-by-step explanation:
Answer:
Part 1: The entry fee is $5
Part 2: Each minute costs 25 cents
Step-by-step explanation:
In the expression, the '+5' represents the fee added to '.25m' the cost per each minute.
X+y=27
x=2y
2y+y=27
y=9
x=27-y
x=27-9=18
Look at the graph, which y values can the graph hit?
Anything above zero would be the right answer, since there is an asymptote at 
.
So the range would be 
Hope this helps.
