Answer:
The box to the left will have the equation p(x) = 5x² and the box to the right will have the equation n(x) =
Step-by-step explanation:

Step-by-step explanation:
The radius r is the distance from the centre to a point on the circle.
Calculate r using the distance formula
r = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (- 5, - 12)
