Answer:
d. (10,800)
Step-by-step explanation:
Vertex appears to be at x = 10
Vertex: (10,800)
The correct answer is the 2nd one
Given,
The expression is,

If x- 3 is the factor of the given polynomial function, then on substituting the value of x = 3 in the polynomial function, it become zero.
Thus subsituting the value of x in the polynomial,

Here, the obtained value of polynomial is 0.
Hence, x-3 is a factor of the given polynomial.
Thus, option A(true) is correct.
