Question 12 • Algebra II
The standard diameter of a golf ball is 42 point 6 7 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 point 0 0 2 mm. Which function could represent this situation?
Answer
A
f of x is equal to x minus absolute value of 42 point 6 7
B
f of x is equal to start absolute value 42 point 6 7 minus x end absolute value
C
f of x is equal to absolute value of x minus 42 point 6 7
D
f of x is equal to 42 point 6 7 minus absolute value of x
