The circumference of a circle varies directly as its diameter. When the diameter of a circle is 6 inches the circumference is 18.84 inches then the diameter of a circle with circumference of 6.28 is?

The diameter is 2

Step-by-step explanation:

We can use a ratio to solve

6              x

 =

18.84      6.28

Using cross products

6 * 6.28 = 18.84x

Divide each side by 18.84

37.68/18.84 = x

2 =x

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
