ALG Quadratic Applications

When I want to find the maximum or minimum height of an object, I should_____.

• Set the equation = 0 and solve.
• Use x = (-b/2a) as my answer.
• Substitute x = 0 into the equation.
• Find the y-coordinate for the vertex.

If I want to find out when an object hits the ground, I should _________.

• Use x = (-b/2a) as my answer.
• Set my equation = 0 and solve.
• Replace x with 0 and evaluate.
• Find the y-coordinate of the vertex.

If I want to see the initial height of an object, I should _____________.

• Substitute x = 0 into the equation and evaluate.
• Use x = (-b /2a) as my answer.
• Find the y-coordinate of the vertex. 
• Set my equation = 0 and solve.

An object flies through the air and follows a parabolic path. What does the y-axis represent? 

• time 
• height from the ground 
• horizontal distance 
• money 

An object flies through the air and follows a parabolic path. Which of these typically represents the x-axis? 

• time 
• height from the ground 

To calculate the TIME that a maximum height occurs, you should use: 

• -b/(2a) 
• Quadratic formula 
• the c value 
• 0

To calculate the maximum height, you should: 

• Use the time you got from -b/(2a) and plug it in for each "t" 
• -b/(2a) 
• use the c value 
• use the b value 

If the graph shows price vs profit, what is the maximum profit? 

• 35
• 12,000
• 12,500
• 60

• September

• October

• November

• December
