Answer:

Explanation:

To find the solutions to the equation x^3 + 2x^2 - x - 2 = log(x + 3), we need to find the points of intersection of the graphs of the two functions f(x) = x^3 + 2x^2 - x - 2 and g(x) = log(x + 3).

The statement that describes the relationship between the graphs and the solutions is:

The solutions are the x-coordinates of the points of intersection of the graphs.

This is because the solutions to the equation are the x-values where the two graphs intersect. At these points of intersection, the y-coordinates of the graphs will be equal, meaning that the left-hand side of the equation (f(x)) and the right-hand side of the equation (g(x)) will be equal. Therefore, we need to find the x-values where f(x) = g(x) in order to find the solutions to the equation.

To visualize this, we can graph the two functions on the same coordinate plane and look for the points where they intersect. The x-coordinates of these points will be the solutions to the equation.

The y-intercepts of the graphs (if they exist) have no relation to the solutions of the equation, as they are simply the points where the graphs cross the y-axis (i.e. where x = 0). Similarly, the x-intercepts of the graphs (if they exist) are not necessarily related to the solutions of the equation, as they only indicate where the graphs cross the x-axis (i.e. where y = 0).
