Which of the functions below could possibly have created this graph!
Answer:
Option D
Step-by-step explanation:
The graph has 3 turning points, therefore a 4th degree polynomial could've been present. The rule is that an nth degree polynomial has n-1 turning points. So Option D is correct.
The function that plots a graph is given from the characteristics of the graph
The option that gives the function that could possibly have created the graph is the option;
Reason:
Therefore; Options (A) and (B) could not have created the graph
Therefore; Option (C) f(x) = x⁵ + 13·x⁴ + 12·x = x·(x⁴ + 13·x³ + 12) could not have created the graph because, x = 0 is not a factor
Which gives;
The function which could possibly create the graph is the option;
D. F(x) = x⁴ - x³ - 3·x² + 3 = (x - 1)·(x³ -3·x - 3)
