Question 1 of 5 • NY-Algebra II Term 1 Hillcrest
Answer:
A graphing calculator can only find real solutions to polynomial equations because it relies on identifying x-intercepts or points of intersection on the Cartesian (x-y) plane. However, some polynomial equations have complex solutions. Because the x-axis only represents real numbers, complex solutions do not appear as x-intercepts, and a system with only complex solutions will not intersect on a standard graph. Therefore, the graphing calculator cannot be used to solve for or approximate these non-real roots.
