Below is an equation that represents an arrow being shot through the air in factored form.
(5 - 2x)(3 + 8x)
How long was the arrow in the air for?
How high was the arrow off the ground when shot through the air?
(use complete sentences in your answer)
x = 2.5
(2.5,0) The arrow was in the air for 2.5 seconds
Multiply the numbers without a variable
y = 3(5) = 15
(0,15) The arrow was 15 feet off the ground when shot in the air
Write the following expression in Standard Form
(x + 6) (x + 4)
x2 + 10x + 24
The following equation represents a rocket being launch in the air. Identify the Velocity (speed) of the rocket (use the correct units)
-16x2 + 135x + 15
Velocity 135ft/sec
Find the x Intercepts
(x + 5) (x + 4)
x = -5, x = -4
(-5, 0) (-4, 0)
Write the following in standard form
(2x + 4) (x + 3)
2x2 + 10x + 12
Create an equation for an arrow being shot in the air given the following information
Height off the ground: 8 ft
Velocity: 120 ft/sec
Gravity: -16t2
f(t)= -16t2 + 120t +8
Identify the x Intercepts
(2x + 8) ( 3x - 9)
x = -4, x = 3
(-4, 0) (3, 0)
Write the following in Standard form
(3x - 2)(2x + 5)
6x2 + 11x - 10
Identify the transformations you would see from the graphs below
x2 to -4x2 - 6
T1: graph turns upside down on the x axis
T2: graph gets thinner by a factor of 4
T3: graph moves down 6 units
Identify the transformations you would see if the equations below were graphed
x2 to (1/2)x2 + 8
T1: the graph would get wider by a factor of 4
T2: the graph would move up 8 units
