Front

What is the equation of a quadratic function with a vertex of (-5, 9) that passes through (-7, -15)?

Back

y = -6(x + 5)² + 9

Front

What is the highest or lowest point on a quadratic called?

Back

Vertex

Front

Identify the vertex of the function f(x) = (x - 4)² + 3.

Back

(4, 3)

Front

What is the green dashed line in a quadratic graph called?

Back

Axis of Symmetry

Front

If f(x) = x², what is the equation of a graph that is 5 units lower?

Back

g(x) = x² - 5

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 the 'a' value in a quadratic function determine?

Back

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

Front

What are the x-intercepts of a quadratic function?

Back

The points where the graph intersects the x-axis, found by solving the equation y = 0.

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).
