Answer: 2x^{2} +15

Explanation:

so basically f(g(x)) is telling you to plug the entire g(x) equation into x in the f(x) equation so it will look like this

2(x^{2} +7) + 1

and then simplify

2x^{2} +14 + 1

2x^{2} +15

One fragment of a given integer n can be selected and its digits reversed (replaced with a right to left version of themselves).
andrew11 [14]

Integers are numbers without decimal points. The number could be positive, negative or zero

<h3>How to determine the maximum number from the integer</h3>

The maximum number from integer N can be determined using the following program written in Python, where comments are used to explain each line

#This prompts the user for input

num = input("Number: ")

#This iterates from 0 to 9

kount = [0 for x in range(10)]

# This iterates through the input, and updates the kount variable

for i in range(len(num)):

  kount[int(num[i])] = kount[int(num[i])] + 1

# This next two lines initialize the greatest number

greatestNum = 0

multiplier = 1

# This iterates through the kount array

for i in range(10):

  #The following is repeated while the current element is greater than 0

while kount[i] > 0:

   #This generates the greatest number

greatestNum = greatestNum + ( i * multiplier )

kount[i] = kount[i] - 1

multiplier = multiplier * 10

#This prints the greatest number

print(greatestNum)
