Question

Task 3: a) A second-degree polynomial in x is given by the expression = + + , where a, b, and c are known numbers and a is not equal to 0. Write a C function named polyTwo (a,b,c,x) that computes and returns the value of a second-degree polynomial for any passed values of a, b, c, and x. b) Include the function written in part a in a working program. Make sure your function is called from main() and returns a value to main() correctly. Have main() use a printf statement to display the returned value. Test the function by passing various data to it and verifying the returned value.

C/C+ program

Answer 1

c code snippet:

Text code:

#include<stdio.h>
//function to return the value
int polyTwo(int a,int b,int c,int x)
{
   //return the value of a*x^2+b*x+c
   return a*x*x+b*x+c;  
}
int main()
{
   //Initializing t as 5 to test the program for 5 various datas
   int t=5;
  
   while(t--)
   {
       int a,b,c,x;
       //taking user input for a,b,c,x
       scanf("%d%d%d%d",&a,&b,&c,&x);
       //the returned value of polyTwo function is stored in answer variable
       int answer=polyTwo(a,b,c,x);
       //printing the answer
       printf("The returned polynomial value is:%d\n",answer);
   }
return 0;  
}
