Understanding the Function F(x) and Its Graph

The video tutorial explores the function F(x) = A * x^n + Bx + 12 over C * x^m + Dx + 12, where M and N are integers and A, B, C, and D are unknown constants. The focus is on determining the possible graph of y = F(x) given limited information, particularly the constant 12. By evaluating F(0), the Y-intercept is found to be 1, which helps in ruling out incorrect graph choices. The tutorial emphasizes the importance of the Y-intercept in graph selection, despite the lack of detailed information about the function's zeros, vertical asymptotes, or discontinuities.
