Final answer:

The x-intercepts of the graph of the given equation are -1000, 500, and 10. The general shape of the graph can be determined by analyzing the polynomial equation.

Step-by-step explanation:

The given equation f(x) = (x + 1000)(x – 500)(x – 10)² is a polynomial equation of degree 4. To find the x-intercepts of the graph, we set the equation equal to zero. This means that at the x-intercepts, the values of f(x) will be zero. By factoring the equation, we can find the x-intercepts as the solutions to the equation.

By factoring the equation, we get (x + 1000)(x – 500)(x – 10)² = 0. The x-intercepts are the values of x that make this equation true. So, the x-intercepts are -1000, 500, and 10.

The general shape of the graph can be determined by analyzing the polynomial equation. Since the degree of the polynomial is 4, we know that the graph will have a total of 4 x-intercepts. Additionally, the graph will exhibit various characteristics based on the signs of the coefficients of the equation. For example, if the coefficient of x^4 is positive, then the graph will open upwards, and if it is negative, then the graph will open downwards.
