If the circumference of a circle is 21.98 feet, what is the diameter of
the circle?
Use 3.14 for pi

diameter = 7 feet

Step-by-step explanation:

Circumference of the circle = pi x d

21.98 = 3.14 x d

d = 21.98/3.14

d = 7 feet

Part 2) The graph in the attached figure N 2

Part 3) The graph in the attached figure N 3

Part 4) The graph in the attached figure N 4

Step-by-step explanation:

Part 1) we have

Find the inverse

Let

y=f(x)

Exchange the variables x for y and y for x

isolate the variable y

------> inverse function

see the attached figure N 1

Part 2) we have

Find the inverse

Let

y=f(x)

Exchange the variables x for y and y for x

isolate the variable y

------> inverse function

see the attached figure N 2

Part 3) we have

Find the inverse

Let

y=f(x)

Exchange the variables x for y and y for x

isolate the variable y

------> inverse function

see the attached figure N 3  

Part 4) we have

Find the inverse

Let

y=f(x)

Exchange the variables x for y and y for x

isolate the variable y

------> inverse function

see the attached figure N 4
