Features of Quadratic Graphs

Front

What is the green dot on the parabola called?

Back

Maximum

Front

Which best describes the vertex of a parabola?

Back

The highest or lowest point of a parabola.

Front

What are the x-intercepts?

Back

The points where the parabola crosses the x-axis.

Front

How many zeros does this parabola have?

Back

The number of x-intercepts of the parabola.

Front

What is the domain of a parabola?

Back

The set of all possible x-values for the parabola.

Front

What is the range of a parabola that opens upwards?

Back

The set of all possible y-values, starting from the vertex to infinity.

Front

What does the vertex form of a quadratic equation look like?

Back

y = a(x - h)² + k, where (h, k) is the vertex.

Front

What is the axis of symmetry in a parabola?

Back

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

Front

How do you find the vertex of a parabola given in standard form?

Back

Use the formula x = -b/(2a) to find the x-coordinate, then substitute to find y.

Front

What is the significance of the 'a' value in a quadratic equation?

Back

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