The domain of this, assuming it's a function, is all real numbers such that x does not equal zero or negative ten.

In interval notation, this is (-∞, -10) U (-10, 0) U (0, <span>∞).

In set builder notation, this is {x | x </span>≠ -10, x <span>≠ 0}.

These inputs are excluded from the domain because they would otherwise allow division by zero. Try plugging in one of the restricted inputs. You'll see that it does not work! On a graph of this </span>function, you will see vertical asymptotes.

Using the C language, write a function that accepts two parameters: a string of characters and a single character. The function

Sav [38]

Answer:

#include <stdio.h>

void interchangeCase(char phrase[],char c){

for(int i=0;phrase[i]!='\0';i++){

if(phrase[i]==c){

if(phrase[i]>='A' && phrase[i]<='Z')

phrase[i]+=32;

else

phrase[i]-=32;

}

int main(){

char c1[]="Eevee";

interchangeCase(c1,'e');

printf("%s\n",c1);

char c2[]="Eevee";

interchangeCase(c2,'E');

printf("%s\n",c2);

}

Explanation:

Create a function called interchangeCase that takes the phrase and c as parameters.
Run a for loop that runs until the end of phrase and check whether the selected character is found or not using an if statement.
If the character is upper-case alphabet, change it to lower-case alphabet and otherwise do the vice versa.
Inside the main function, test the program and display the results.

You are troubleshooting a mobile device that will not pair with a Bluetooth headset. The device was functioning properly with th

bulgar [2K]

Answer:

B. Replace the Bluetooth headset with a new pair.

Explanation:

Since all other mobile devices, after receiving the "corporate-wide" OS update, aren't having issues with pairing with Bluetooth headsets, we can safely conclude that the OS update isn't the issue.

To find out if the Bluetooth headset is not the culprit, we can try to pair the mobile device with a different headset. If it pairs correctly, then we can conclude that the old Bluetooth headset might have a fault, or it might need to be disconnected/forget from the device and paired gain.

Write a Python 3 program that prompts the user for 3 postive numbers (or zero) and then adds them together. If the user enters a

Citrus2011 [14]

Answer:

def prompt_number():

while True:

number = int(input("Enter a number: "))

if number >= 0:

break

return number

def compute_sum(n1, n2, n3):

total = n1 + n2 + n3

return total

n1 = prompt_number()

n2 = prompt_number()

n3 = prompt_number()

result = compute_sum(n1, n2, n3)

print(result)

Explanation:

Create a function named prompt_number that asks the user to enter a number until a positive number or 0 is entered and returns the number

Create a function named compute_sum that takes three numbers, sums them and returns the sum

Ask the user to enter three numbers, call the prompt_number() three times and assign the values

Calculate the the sum, call the compute_sum and pass the numbers as parameters

Print the result
