A safety regulation states that the height h of a guardrail should be 106 centimeters with an absolute deviation of no more than
1 answer:
Answer: We are given:
The height h of a guardrail = 106 centimeters
Absolute deviation = 7 centimeters
The absolute value inequality is
To find the acceptable heights of a guardrail , we add and subtract absolute deviation(7) from the mean height(106)
The acceptable range of height is:
106 + 7 = 113
106 - 7 = 99
Acceptable heights are defined by
Therefore, the acceptable range of heights of a guardrail are 99 cm to 113 cm.

Answer: Second Option
Step-by-step explanation:
The exponential growth functions have the following form:
Where a is the main coefficient, b is the base and x is the exponent.
For this type of functions the base b must always be greater than 1. Otherwise it would be an exponential decay function
Among the options given, the only function whose base is greater than 1 is the second option:
