Respuesta :

Answer:

B

Step-by-step explanation:

If the values of x and function are (0,3),(2,1),(4,0),(5,-2) then the factor of function may be (x-3) which is option c.

What is function?

Function is relationship between two or more that are variables expressed in equal to form. In a function each value of x must have a corresponding value of y.

How to form function?

We have been given values of x and corresponding values of function. Take two points and form equation.

Equation from two points can be calculated by following formula:

[tex](y-y_{1}) =(y_{2} -y_{1} /x_{2} -x_{1} )(x-x_{1} )[/tex]

where [tex](x_{1} ,y_{1} ),(x_{2} ,y_{2} )[/tex] are the two points.

Equation is as under:

y-3=(1-3/2-0)*(x-0)

y-3=-2/2(x)

y-3=-x

y=-x+3

y=-1(x-3)

There are two factors of the function -1 and (x-3).

Hence if the values of x and function are (0,3),(2,1),(4,0),(5,-2) then the factor of function may be (x-3) which is option c.
