Back

parabola

Front

What key feature tells the initial height of the roller coaster?

Back

y-intercept

Front

How high was the ball when it was thrown? Choose the key feature and the answer.

Back

y-intercept, 3 feet

Front

What is the vertex of a quadratic graph?

Back

The highest or lowest point on the graph, depending on the direction of the parabola.

Front

What does the axis of symmetry represent in a quadratic graph?

Back

A vertical line that divides the parabola into two mirror-image halves.

Front

What is the significance of the x-intercept in a quadratic graph?

Back

The points where the graph intersects the x-axis, indicating the solutions to the equation.

Front

What does the y-intercept represent in a quadratic graph?

Back

The point where the graph intersects the y-axis, indicating the value of the function when x=0.

Front

How can you determine the maximum or minimum value of a quadratic function?

Back

By finding the y-value of the vertex.

Front

What is the standard form of a quadratic equation?

Back

y = ax^2 + bx + c, where a, b, and c are constants.

Front

What does the 'a' value in a quadratic equation indicate about the graph?

Back

It determines the direction of the parabola (upward if a > 0, downward if a < 0).
