Front

What is the green dashed line called?

Back

Axis of symmetry

Front

Describe the transformation of the graph of f(x) = x² to g(x) = -4x².

Back

Reflected, narrower

Front

What is the axis of symmetry of the function y = x² - 2x + 1?

Back

x = 1

Front

Identify the vertex and whether the graph opens up or down for the function y = x² + 4x + 4.

Back

Vertex: (-2, 0); opens up

Front

Does the graph of y = -x² + 4 have a maximum or minimum value?

Back

Maximum

Front

What are the roots or x-intercepts of the function y = x² - 4?

Back

x = -2 and x = 2

Front

What is the standard form of a quadratic function?

Back

y = ax² + bx + c

Front

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

Back

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

Front

What does it mean for a parabola to open upwards?

Back

The coefficient of x² is positive.

Front

What does it mean for a parabola to open downwards?

Back

The coefficient of x² is negative.
