Call your class quadraticExpression.
• Your private data will be a, b, c. Make them doubles.
• Create an enumerated list with
o NO_ROOTS = 0
o ONE_ROOT = 1
o TWO_ROOTS = 2
o INFINITE_ROOTS = 3
• Write the constructor as stated in the book
• Write the changeCoeeficients as stated in the book
• Write the getACoeeficient, getBCoeeficient,
getCCoeeficient as inline constant functions
• Write evaluate function to take a double a return a double. Constant
function.
• Write getNumberOfRoots function to return an integer. Constant
function.
• Write getFirstRoot and getSecondRoot to return the first and second
roots. Return a domain_error is there is no first or second root.
Constant Functions.
Use my .cpp file to test out your class.

#include <iostream>
#include "quadraticExpression.h"
using namespace std;
void evaluateExpression (const quadraticExpression &);
int main()

quadraticExpression q[6] = { quadraticExpression (2.1, 3, -7),
quadraticExpression (1.4, 3.9, +7),
}
for (int i=0; i<6; i++)
return EXIT_SUCCESS;
}
void evaluateExpression (const quadraticExpression &q)
{
int errorsHandled = 0;
evaluateExpression(q[i]);
cout << "f(-5) " << q.evaluate(-5) << endl;
cout << "f(0) = " << q.evaluate (0) << endl;
cout << "f(5) = " << q.evaluate (5) << endl;
if (q.getNumberOfRoots() == INFINITE_ROOTS)
}

try {

ONE_ROOT)
cout << "The Expression has One Root at x = " << q.getFirst Root() << endl;

q.getFirstRoot();
(domain_error e) {
errorsHandled ++;

q.getSecondRoot();
quadraticExpression (-.75, 0, 0),
quadraticExpression (0, .3, -7),
quadraticExpression (0, 0, 4),
quadraticExpression());
