I am not sure what you ae asking. If you are asking where f(x) and g(x) intercept, they would have the same (x,y) value
y = 11x^{6}
y = 2x^{7}
Use a graphing calculator or math computer program. This is almost impossible to do by table or graph because the numbers are so large. Graph the two equations and see where they intersect. The (x,y) coordinate that matches both of the functions is the answer. Both functions have (0.0) as a common coordinate, but that may not be the only coordinate they have in common.
The Special Product is the process by which terms are multiplied (x+6)(x6) = x^{2}  36.
This is a parabola with the point at (0,36) and cross the x axis at 6 and 6 (y = 0)
Sorry I can't help you more. Hope this helps.
