f(x)=x2
What is (0, 0)
The height of a projectile is modeled by the equation f(x)=-8(x-2)2 +10 where f(x) is the height in feet and x is the seconds. After how many seconds is the projectile at its highest point? What is the highest point the projectile reaches?
What is 2 seconds and 10 feet.
Given the x/y table, what is the value of a? x|y -1|4 0|3 1|4
What is 1
f(x) = x2 + 3
What is up 3
f(x) = 3(x - 4)2 - 6
What is x = 4
f(x)=-2(x+7)2
What is (-7, 0)
The height of a ball, h meters, in t seconds is given by the function h= -5(t-3)2 + 46.5. That is the maximum height of the ball?
What is 46.5 meters
f(x) = (x+4)2
What is left 4
f(x) = 3(x - 6)2 - 6
What is x = 6
f(x) = 9(x + 5)2 - 10
What is (-5, -10)
The cost in C dollars of operating a machine per day is given by the function C= 2(x - 5)2 + 25. What is the minimum cost to operate the machine?
What is $25.
f(x) = -2x2
What is flip, stretch by 2
f(x) = (x + 7)2 - 4
What is x = -7
f(x) = -10(x)2 - 4
What is (0, -4)
A quarterback passed the ball to a receiver 40 meters downfield. The path of the ball can be described by the equation h= (x - 2)2 + 24 where x is seconds and h is meters. When does the ball reach its maximum height?
What is 2 seconds.
f(x) = (x-3)2 +4
What is right 3 up 4
f(x) = (x +10)2 - 2
What is x = -10
f(x) = -1000(x + 893)2 - 2009
What is (-893, -2009)
A missile is launched and the function
f(x)= -2(x-18)2 - 648 represents its path where f(x) is the height of the missile. A plane is flying at a height of 650 feet. Is the plane in danger? Why?
What is no, the missile only reaches 648 feet
Double Points everyone
Double
f(x) = 1/2(x+2)2 +3
What is left 2, up 3, stretch by 1/2
f(x) = (x + 0.5)2 - 2.5
What is x = -0.5
