Graphing Quadratics Review

Front

What is the equation for the axis of symmetry of a quadratic function?

Back

x = h, where h is the x-coordinate of the vertex.

Front

The axis of symmetry passes through which coordinate?

Back

The x-coordinate of the vertex.

Front

What are the green dots called in a quadratic graph?

Back

Roots or x-intercepts.

Front

What does it mean if a quadratic function is vertically stretched by a factor of 2?

Back

The graph is pulled away from the x-axis, making it narrower.

Front

What does it mean if a quadratic function is vertically compressed by a factor of 2?

Back

The graph is pushed towards the x-axis, making it wider.

Front

How do you identify the vertex of a quadratic function in standard form?

Back

The vertex can be found using the formula (h, k) where h = -b/(2a) and k is the function value at h.

Front

What is the general form of a quadratic equation?

Back

y = ax^2 + bx + c.

Front

What transformation is represented by the equation y = -(x+2)^2 - 5?

Back

Reflection across the x-axis, shifted left 2 units, and down 5 units.

Front

What is the significance of the vertex in a quadratic function?

Back

The vertex represents the maximum or minimum point of the parabola.

Front

How do you find the x-intercepts of a quadratic function?

Back

Set y = 0 and solve the equation ax^2 + bx + c = 0.
