What keywords should you look for in quadratic word problems to identify that you need to find the vertex?

• sum, difference

• product, quotient

• average, median

• max, min, least, greatest

What is the formula for finding the vertex in a quadratic equation?

• X = -B / 2A

• X = -C / 2B

• X = A / 2B

• X = B / 2C

In the context of the toy rocket problem, what does the initial 30 meters represent?

• Maximum height

• Height of the building

• Time of flight

• Initial velocity

How do you calculate the time at which the rocket reaches maximum height?

• Multiply B by -2A

• Divide -B by 2A

• Add B to 2A

• Subtract B from 2A

What is the maximum height reached by the toy rocket, according to the calculation?

• 94 meters

• 64 meters

• 83 meters

• 30 meters
