Question

Write a function that computes the value of the polynomial 3x5+2x4-5x3-x2+7x-6 . Write a program that asks the user to enter a value for , calls the function to compute the value of the polynomial, and display the value returned by the function.

Answer 1

#include <stdio.h>
// Function for computing the value of the polynomial
double function(double x)
{
return 3*x*x*x*x*x + 2*x*x*x*x - 5*x*x*x - x*x + 7*x - 6;
}
int main()
{
double x;
scanf("%lf", &x);

// Calling the function and saving the answer
double answer = function(x);
printf("Answer = %lf", answer);

return 0;
}
