I believe the answer is D.infinite solutions
Answer:
True - ![R=(5,\infty) , y|y>5](https://tex.z-dn.net/?f=R%3D%285%2C%5Cinfty%29%20%2C%20y%7Cy%3E5)
Step-by-step explanation:
Given : The range of the function given below is the set of all positive real numbers greater than 5 , ![f(x)=5+4^x](https://tex.z-dn.net/?f=f%28x%29%3D5%2B4%5Ex)
To find : The given statement is true or false?
Solution :
Domain of the function is where the function is defined
The given function
is an exponential function
So, the domain of the function is,
![D=(-\infty,\infty) , x|x\in \mathbb{R}](https://tex.z-dn.net/?f=D%3D%28-%5Cinfty%2C%5Cinfty%29%20%2C%20x%7Cx%5Cin%20%5Cmathbb%7BR%7D)
i.e, The set of all real numbers.
Range is the set of value that corresponds to the domain.
Let ![y=5+4^x](https://tex.z-dn.net/?f=y%3D5%2B4%5Ex)
If ![x\rightarrow \infty , y\rightarrow 5](https://tex.z-dn.net/?f=x%5Crightarrow%20%5Cinfty%20%2C%20y%5Crightarrow%205)
If ![x\rightarrow -\infty , y\rightarrow \infty](https://tex.z-dn.net/?f=x%5Crightarrow%20-%5Cinfty%20%2C%20y%5Crightarrow%20%5Cinfty)
So, The range of the function is
![R=(5,\infty) , y|y>5](https://tex.z-dn.net/?f=R%3D%285%2C%5Cinfty%29%20%2C%20y%7Cy%3E5)
Therefore, The given statement is true.
Answer: Most ethanol in the United States is produced from starch-based crops by dry- or wet-mill processing. Nearly 90% of ethanol plants are dry mills due to lower capital costs. Dry-milling is a process that grinds corn into flour and ferments it into ethanol with co-products of distillers grains and carbon dioxide.
