Expert Solution

Answer to Problem 12E

The correct answer is II.

  Precalculus: Mathematics for Calculus - 6th Edition, Chapter 3.2, Problem 12E

Explanation of Solution

Given information:

The polynomial function is S(x)=12x62x4

The power of the equation is even and the leading co-efficient positiveso, predict the end behaviour, which is when x approaches positive , y will approach positive and as x approaches negative , y will approach positive .so, graph IIand VI contain this characteristic. Now substitute x with any value

  12162(1)4                          [substitute the value of x]122                                        [evaluate power]0.52                                     [divide]1.5                                           [subtract]

Therefore ,the coordinate point (1, 1.5 ),the graph II contain this closest

Hence, the correct answer is II.
