Question 4 • Mathematics III
The solutions are the x-values that make the two sides equal, so they occur where the graphs y = x² − 2x − 4 and y = −3x + 9 intersect. Setting the expressions equal gives x² + x − 13 = 0, whose solutions are x = (−1 + √53)/2 and x = (−1 − √53)/2. These are the x-coordinates of the intersection points, as choice B states.
