IM2 Unit 2 Review (Quadratic Functions)

Front

What is the graph of a quadratic function called?

Back

Parabola

Front

Convert the equation y= x² + 4x + 11 into vertex form.

Back

y = (x + 2)² + 7

Front

The axis of symmetry line passes through which point?

Back

Vertex

Front

What relationship does the vertex of a parabola always have with the x-intercepts?

Back

It's the average (middle) of the x-intercepts.

Front

What are the x-intercepts of the function y = x² + 6x + 5?

Back

(-5, 0) and (-1, 0)

Front

Define a parabola.

Back

A parabola is a U-shaped graph that represents a quadratic function.

Front

What is vertex form of a quadratic function?

Back

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

Front

How do you find the vertex of a parabola given in standard form?

Back

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

Front

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

Back

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

Front

What is the axis of symmetry for the quadratic function y = ax² + bx + c?

Back

The axis of symmetry is x = -b/(2a).
