The answer to this question is B!
Answer:
f'(x) = 
Step-by-step explanation:
i) f(x) = 9 / x
ii) f'(x) = 
There are an infinite number of possibilities, and not enough information
to decide which possibility is really the one inside the function machine.
Here are a few. Each of these gives the result that you described,
and there are an infinite number of others:
f(x) = x
f(x) = 2x + 1
f(x) = 10x + 9
f(x) = x² - 2
f(x) = 7x² - 8
f(x) = 31x³ + 30
f(x) = log( |x| ) - 1
f(x) = ln( |x| ) - 1
f(x) = x tan(45°)

Answer:
The percent of increase in height of the stalks is 20%.
Step-by-step explanation:
The general formula for a percent increase is as follows: (Original Amount - New Amount/Original Amount) x 100. The original height of the stalks was 60 inches tall. The new height of the stalks is 72 inches. In the numerator of our fraction, we take 72-60 to get 12. Our denominator is the original amount, or 60. This gives us an overall fraction of 12/60, which when we divide gives us 0.2. Once we multiply our decimal by 100, we get an overall percent increase of 20%.
