用C语言绘制y=x*x*x-2x*x+x-3的图像

Question

#include <stdio.h>
#include <stdlib.h>

/* run this program using the console pauser or add your own getch, system("pause") or input loop */

float f(float x)
{
float y;

  y=x*x*x -2*x*x +x -3;
  
  return y;

};

int main(int argc, char *argv[]) {

float x;

for(x=-2.0;x<=2.1;x=x+0.1)
    printf("x=%f  y=%f \n",x,f(x));

return 0;

}
绘制代码增加？

参考一下吧，有你要的三次方方程的曲线绘制
把22行改成你的公式，选择1，设定x的取值范围就能绘制了
