Owen has enough materials to build up to 10 birdhouses in shop class. Each birdhouse needs 12 square feet of wood. Function W(b) = 12b represents the total amount of wood that Owen would need to build b birdhouses. Discrete or Continuous?

Continuous

Given that a function, g, has a domain of -20 ≤ x ≤ 5 and a range of -5 ≤ g(x) ≤ 45 and that g(0) = -2 and g(-9) = 6, select the statement that could be true for g.

A

Relation

What is the domain and range of this situation?

0-70 and 0-500

If you want to make the change on a graph look big what should you do to the range?

Make the range as small as possible so the change looks larger.
