A farmer is tracking the number of soybeans his land is yielding each year. He finds that the function f(x) = −x2 + 20x + 100 mo
labwork [276]

Answer:

The farmer should expect to LOSE 10 pounds of soybeans per acre per year

Step-by-step explanation:

f(x)=-x^2 + 20x + 100

just find how many soybeans his land will yield (per acre) after 10 and 20 years:

After 10: 200 pounds of soybeans/acre

After 20: 100 pounds of soybeans/acre

Because 10 years have passed and they lost 100 pounds of soybean production per acre, the farmer should expect to lose 10 pounds of soybeans per acre per year (-10 pounds of soybeans per acre/year)

What is the domain of the function y = l n (StartFraction negative x 3 Over 2 EndFraction).
Ymorist [56]

The domain of the provide function where the function is defined is x less than the number three.

<h3>What is the domain of the function?</h3>

Domain of a function is the set of all the possible input values which are valid for that function.

The function given in the problem is,

y=\ln\left(\dfrac{-x+3}{1}\right)

The above function is the function of logarithm. For the logarithmic function, it is defined for all the real numbers except 0.

Thus, the function should be greater than zero as,

\left(\dfrac{-x+3}{1}\right) > 0\\(-x+3) > 0\\-x > -3

Change the sign of both side, by changing the inequality,

x < 3

Thus, the domain of the provide function where the function is defined is x less than the number three.
