2

Front

What does the equation y = -3x^2 + 7x - 2 represent in terms of its opening direction and vertex?

Back

Opens down with a maximum.

Front

What does x = -b/2a calculate in a quadratic function?

Back

Axis of symmetry.

Front

What is the orange line in a quadratic graph called?

Back

Axis of Symmetry.

Front

What is the standard form of a quadratic function?

Back

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

Front

What does the 'a' value in a quadratic function determine?

Back

The direction of the parabola's opening (upward if a > 0, downward if a < 0).

Front

What is the vertex of a quadratic function?

Back

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

Front

How do you find the y-intercept of a quadratic function?

Back

Set x = 0 in the equation and solve for y.

Front

What is the axis of symmetry in a quadratic function?

Back

A vertical line that divides the parabola into two mirror-image halves, given by x = -b/2a.
