Quadratic Applications

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

• time the object is in the air

• height of the object from the ground

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

• time the object is in the air

• height from the ground

Define Roots, Zeros, X-intercept, and Solutions

• Where the parabola touches or intersects the x-axis

• Where the parabola touches or intersects the y-axis

Define Maximum

• The lowest y-value on the graph

• The highest y-value on the graph

Define Minimum

• The lowest y-value on the graph

• The highest y-value on the graph

For a projectile whose equation is written in standard form:

y = ax² + bx + c, which letter tells us the starting/initial height (the y-intercept)?

• a

• b

• c

• x

What is the initial (starting) height of an object following this path?

h(t) = -16t² +20t + 6

• -16 feet

• 0 feet

• 20 feet

• 6 feet

When did the ball reach its maximum height? Choose the key feature and the answer.

• y-intercept, 3 secs

• x-value of the vertex, 4 secs

• y-value of the vertex, 5 secs

• y-intercept, 0 secs
