Step-by-step explanation:
We need to find the value of the function at the indicated value.

Indicated values are : f(-7), f(0), f(6), f(7)
To find f(-7), put x = -7 in the given function

To find f(0), put x = 0 in the given function

To find f(6), put x = 6 in the given function

To find f(7), put x = 7 in the given function

Hence, this is the required solution.

Answer: Radius = 1,250
Step-by-step explanation: The circumference of a circle equals the 2 x radius x π.
The formula to solve the radius is 2r x 3.14 = 7,850
Divide both sides by 3.14 = 2r = 2,500
Divide both sides by 2 = r = 1,250.
The radius = 1,250
