Chapter 6.4, Problem 57HP

To determine

To find: the degree of the function from the graph and choose the correct option.

Answer to Problem 57HP

The degree of the polynomial equation is $4$ .

The option $C$ is correct.

Explanation of Solution

Given:

  

Options are:

  

Concept used:

The degree of the polynomial from the graph is the number point which cut the $x$ -axis.

Calculation:

According to the given:

The graph of the polynomial function $f\left(x\right)$ .

From the graph the curve cut the $x$ -axis at $4$ points which means there is four zeroes.

The number of roots is equal the number of the degree of the function.

Since, there is $4$ roots there will be $4$ degree of the polynomial equation.

Hence, the degree of the polynomial equation is $4$ .
