The graph of a rational function has local maxima at (-1,0) and (8,0). the complex number 2+3i is a zero of the function. what is the least possible degree of this function? (answer choices included)

a. 3
b. 4
c. 5
d. 6

Any polynomial's graph cannot have two simultaneous maxima, so they must contain a minima between them. Thus, the total number of turning points of the graph is 3. Generally, when plotting a polynomial, the number of turning points is:
n = d -1; where d is the degree of the polynomial and n is the number of turning points. Thus, this function's degree must be at least 4. The answer is b.

If gravity is one third on mars then weight also one third on mars
