What is the range of the function graphed below?

Range =

===================================================

Explanation:

The range is the set of all possible y values of a function.

The lowest point happens when y = -3. We exclude this y value because of the open hole.

The highest point is at y = 3 which is included because of the filled in circle.

The range can be written as meaning y is between -3 and 3, excluding -3 but including 3.

Side note: The range in interval notation is (-3, 3].

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
