Question

Write three different polynomial functions such that f(3) = 2.

Answer 1

1.
`f (x) = x-1`

2.
`f (x) = x^2-7`

3.
`f (x) = x^3-25`

Explanation:

Many polynomials can be formulated so that
`f(3) = 2`, some are as follows:

1.
`f (x) = x-1`

verification:

`f (3) = 3-1 = 2`

meets the condition.

2.
`f (x) = x^2-7`

verification:

`f(3)=3^2-9=9-7=2`

also meets the condition

3.
`f (x) = x^3-25`

verification:

`f (3) =3^3-25=27-25 = 2`

It is also valid.
