Flashcardizz: Review for the test Quadratic functions

Front

What is a quadratic function?

Back

Front

What does the graph of a quadratic function look like?

Back

The graph of a quadratic function is a parabola, which can open upwards or downwards depending on the sign of the coefficient 'a'.

Front

What is the vertex of a parabola?

Back

The vertex is the highest or lowest point of the parabola, depending on its orientation.

Front

How do you find the maximum height of a projectile?

Back

Front

What does the term 'initial height' mean in projectile motion?

Back

Initial height refers to the height from which an object is thrown or dropped, represented by the constant 'c' in the quadratic equation.

Front

What is the formula to calculate the time when a projectile hits the ground?

Back

Front

What is the significance of the coefficient -16 in height equations?

Back

The coefficient -16 represents the acceleration due to gravity in feet per second squared, affecting how quickly the object falls.

Front

What does the term 'upward velocity' mean?

Back

Upward velocity refers to the speed at which an object is thrown upwards, measured in feet per second.

Front

How do you determine the time it takes for an object to reach the ground?

Back

You can determine the time by solving the quadratic equation for when height equals zero.

Front

What is a solution to a system of equations?

Back

A solution to a system of equations is a set of values that satisfy all equations in the system simultaneously.
