Question

Write a program called problem1.cpp that produces a table showing sample point co-ordinates on a parabola. The program should contain a function that takes in a given value of x and produces the corresponding value of y according to the equation y=x^2+x+1. The main program should then range the x values from -10 to 10, printing all the x and y co-ordinates of the corresponding points on the screen.(15 points)

Answer 1

#include <iostream>
#include <math.h>
using namespace std;

//function that accepts x to generate value of y according to parabolic equation y=x^2+x+1.

int genParabolaPoints(int x)
{
int z=pow(x,2); //power function to calculate square of x ,or you can use x*x also
int y=z+x+1;
return(y);
}

int main()
{
// loop to check for all integer values of x between -10 and 10
for(int x=-10;x<=10;x++)
{

cout<<"("<<x<<","<<genParabolaPoints(x)<<")"<<"\n"; //generating the coordinates of all points on parabola for value of x lying between -10 and 10

  
}
return 0;
}
