What are the center and intercepts of the conic section? What are the domain and range?
Design Two patterns, such as arrays of dots or lines, can overlap to form moiré patterns. In the diagram, what pattern do the intersecting ripples form? Which of these equations is a possible model for the pattern:
The intersecting ripples form a circle.
How can you identify a possible model?
Find the type of conic section represented by each equation.
The equation
Graph each equation. Find the lines of symmetry, the domain, and the range.
Identify the domain and range.
