The graph of the equation intersects the x-axis at two points, which means there are two x-intercepts. We can use the zero (or root) of the equation to approximate these intercepts. Using a graphing calculator or software, we can find that the zeros of the equation are approximately 0.94 and 2.18. These values are closest to those in choice A, so the best answer is A.
