Answer 1

Answer:

  see attached

Step-by-step explanation:

A quadratic relation is a polynomial relation that has a highest degree of 2. Its graph is ⋃-shaped (or ⋂-shaped). That is, it decreases, then increases, or vice-versa.

__

To identify the quadratic relations, you check to see which of them matches the description above.

(a)

The highest degrees, left to right, are 1, 3, 2. The right-most equation is a quadratic relation

(b)

The left-most graph is ⋃-shaped, so represents a quadratic relation.

(c)

The y-values in the left table decrease, then increase, suggesting a quadratic relation. (Those in the right table continue to decrease at a constant rate, which represents a linear relation.)
