Question

The standard diameter of a golf ball is 42.67 mm. A golf ball factory does quality control on the balls it manufactures. Golf balls are randomly measured to ensure the correct size. One day, an inspector decides to stop production if the discrepancy in diameter is more than 0.002 mm. Which function could represent this situation?
A. f(x ) = x – |42.67|
B. f(x ) = |x| – 42.67
C. f(x ) = |42.67 – x|
D. f(x ) = 42.67 – |x|

Answer 1

C. f(x ) = |42.67 – x|

Answer 2

Answer:

C

Step-by-step explanation:

This is because since the inspector wants the golf balls he makes to make no more than .002 away from the standard diameter,

You would subtract x from the standard diameter in the absolute value symbols to represent the distance away from the ball subtracted or added from 42.67
