Question

Lorraine writes the equation shown. x squared + y minus 15 = 0 She wants to describe the equation using the term relation and the term function. The equation represents .

Answer 1

A

Explanation:

The answer is A

Answer 2

The equation represents: A relation and a function

Explanation:

A function is said to be a relation; however, the relation does not have to function. For a relation to result in a function, then every input gives an important output. Thus; the given information x² + y - 15 = 0 can be re-written as:

y = - x² + 15

Similarly, the equation typically illustrates a relation as well. Consequently, suppose we replace any x-value for x, then the one possible output will be for y. Hence, that is also a function.
