Question

Write a c program that calculates the value of y for the quadratic equation given below by assuming x= 5 y = ax 2 • bx c the program must ask the user to enter the values of a, b, and c within any range from 1 to 5 you can check the answer with a calculator to verify your program rubric: correct use of the main function correct use of the command syntax correct program output total is 20 points

Answer 1

A sample C program is provided that calculates the value of y using the quadratic equation y = ax^2 + bx + c where x=5 and a, b, c are inputted by the user within the range of 1 to 5.

Step-by-step explanation:

The student has asked for a C program to calculate the value of y for a quadratic equation with a given x of 5. The quadratic equation is y = ax^2 + bx + c. The user should be able to enter values for a, b, and c within the range of 1 to 5, and the program will compute the value of y. Below is a sample C program that accomplishes this task:

#include <stdio.h>

int main() {
float a, b, c, x = 5, y;
printf("Enter the values for a, b, and c (1-5): ");
scanf("%f %f %f", &a, &b, &c);
y = a * x * x + b * x + c;
printf("The value of y is: %.2f", y);
return 0;
}

This program first includes the standard input-output header file <stdio.h>. In the main function, it declares float variables for a, b, c, and initializes x to 5. It then prompts the user to input the values for a, b, and c, reads them using scanf, calculates y using the given formula, and outputs the result.
