• The volume of the balloon increase at a constant rate, decreases, then stays constant, then increases, then constant, and increases at a constant rate.  

Is this graph continuous or discrete?

• Continuous

• Discrete

What is the range of the graph? (a)  

• ≤ x ≤ 5

• < x < 5

• ≤ y ≤ 5

• < y < 5

Evaluate f(1)

• 0

• 1

• 2

• 4

What is f(0)?

The graph is a picture of both ​ (a)  

• relation

• function

• domain

• range

• x-intercept

• y-intercept

• rate of change

• minimum

• maximum

• extrema

Answer explanation

Extrema are both the highest (maximum) point and the lowest (minimum) points.
