Question
![(20 min) Examine the following incomplete C++ program, which evaluates a mathematical
formula given as
9x3 – 27x? – 4x + 12
y =
V3x2 +1 + |5 – x4|
(1)
tinclude <iostream>
using namespace std;
/* a. Write the definition for function myFunc () */
int main ()
{
double x, y;
cout « "Enter value x: ";
cin >> x;
y = myFunc (x);
/* b. Write the statements that print out the values of x and y,
as well as a simple description of y */
In this program, myFunc () is a function which receives a user-input value x and returns value :
as in Eqn (1). The last part of the program should print out the values of a and y, together with
a simple description for y. The description for y should be different, depending on the value of
y, as shown in the following table.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd911cf9a-d01b-41a6-be72-d88d8aa52e5a%2F2ddafb71-6931-4658-bf63-20e895ff52f9%2Fhwtyck_processed.png&w=3840&q=75)
