What is the answer please. need help

is the function of the least degree has the real coefficients and the leading coefficients of 1 and with the zeros -1, 5, and 2.

Step-by-step explanation:

Given the function

As the highest power of the x-variable is 3 with the leading coefficients of 1.

solving to get the zeros

             ∵  

as

so

Using the zero factor principle

if  

Therefore, the zeros of the function are:

is the function of the least degree has the real coefficients and the leading coefficients of 1 and with the zeros -1, 5, and 2.

Therefore, the last option is true.
