Quadratic y = x2 + k Practice
1. In each picture, the graph of y = x2 is shown as a dotted parabola (standard position).
The solid parabola is the graph of a quadratic relation of the form y = x2 + k.
For each solid parabola, is the value of

Introducing The Parabola
The graph of a _quadratic_ relation is called a _parabola_. The parabola has some
important features:
_axis of symmetry_
_zero_
_zero_
_y - intercept_
_optimal value_
_vertex_
