Respuesta :
According to the number of roots, the function is of the 4th degree.
----------------------
- A root of a function f(x) is a value of x for which f(x) = 0.
- When a function changes the signal, from negative to positive or vice-versa, there is a root.
- A function of the nth degree has n roots.
In the table:
- Changes signal between x = -2 and x = -1, thus, there is one root.
- When x = 0, y = 0, thus another root.
- Between x = 0 and x = 1, it decreases, thus there is the 3rd root.
- Changes signal between x = 1 and x = 2, thus, this is the 4rd root.
- Since the function has 4 roots, it is of the 4rd degree.
