Quadratics Review (axis of symmetry, vertex)

Front

What is the maximum/minimum of a parabola called?

Back

vertex

Front

What is the y intercept for the equation: y = -8x² + 3x - 7?

Back

(0, -7)

Front

What is the axis of symmetry?

Back

the dividing line for a parabola

Front

What do we call the graph of a quadratic function?

Back

parabola

Front

Does the equation open up or down? Y = -3x² + 7x - 2

Back

down

Front

What is the standard form of a quadratic equation?

Back

y = ax² + bx + c

Front

How do you find the vertex of a parabola 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 the 'a' value in a quadratic equation determine?

Back

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

Front

What is the formula for the axis of symmetry in a quadratic equation?

Back

x = -b/(2a)

Front

What is the vertex form of a quadratic equation?

Back

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