what is maximum no. of point of intersection of graph of 2 different cubic polynomial function with leading coefficient equal to 1
a.)2
b.)3
c.)9
d.)6

• Finding the number of solutions to p(x) = q(x) will find the number of intersections of the two graphs.
  
  
  This is also equivalent to the number of roots of p(x) - q(x) = 0. Since p(x) and q(x) are both third degree polynomials with a leading term of x^3, the x^3 term will drop out, leaving at most a third degree polynomial (cubic) on the left side. By the Fundamental Theorem of Algebra, a 2nd degree polynomial can have at most 2 real solutions, leading to an answer of 2.

  let us assume two polynomial functions p(x) and q(x)This is also equivalent to the number of roots of . Since and are both third degree polynomials with a leading term of , the term will drop out, leaving at most a second degree polynomial (cubic) on the left side. By the Fundamental Theorem of Algebra, a second degree polynomial can have at most real solutions, leading to an answer of .
