Find the vertex.
y = x2 + 16x + 71
(-8, 7)
(-8, 3)
(4, 10)
(4, -2)
Find the vertex.
y = 2x2 - 28x +94
(14, -3)
(14, 9)
(7, 10)
(7, -4)
y = -x2 + 12x - 40
y = - (x-6)2 - 4
y = - (x-6)2 - 76
y = - (x-6)2 + 4
y = - (x-6)2 + 76
x2 + 6x = 5
0 = (x + 3)2 - 5
0 = (x + 6)2 - 9
0 = (x + 3)2 - 14
0 = (x + 6)2 - 14
f(x) = x2+6x+9
f(x) = (x-3)2+18
f(x) = (x+3)2+18
f(x) = (x+3)2
f(x) = (x-3)2
How high would you jump if the equation, in feet per second, for jumping from a cliff is:
h(t) = -16t2 + 8t + 24?
25 feet
24 feet
27 feet
26 feet
h(t) = -16t2 +128t
When will the object reach its maximum height?
The profit from selling local ballet tickets depends on the ticket price. Using past receipts, we find that the profit can be modeled by the function p=-15x2+600x+60 , where x is the price of each ticket. What is the maximum profit you can make from selling tickets?
$6060
$20
$300
$10,250
A ball is thrown into the air with an upward velocity of 100 ft/s. Its height, h, after t seconds is given by the function
h = -16t2 + 64t + 960.
How many seconds did it take for the ball to reach its maximum height?
1 second
4 seconds
3 seconds
2 seconds
A dolphin jumps from the water at at initial velocity of 16 feet per second. The equation h = -8t2 + 16t models the dolphin's height at any given time, t. What is the maximum height the dolphin jumps?
1 foot
5 feet
7 feet
8 feet
12 feet
