Simplest polynomial function is x^4-x^3-11x^2+9x+18.

Solution:

Given data:

Zeroes are 3i, –1, 2.

3i is a complex root of the function.

If 3i is a zero of the polynomial then –3i is also a zero of the polynomial.

Therefore zeroes are 3i, –3i –1, 2.

By factor theorem,

If a is zero of the function, then (x – a) is a factor of the polynomial.

So, the factors are (x – 3i), (x + 3i), (x + 1), (x –2).

On multiplying the factors, we get the polynomial.

(x - 3i) (x + 3i) (x + 1) (x -2)

            =(x^2+3ix-3ix+(3i)^2)(x^2-2x+x-2)

            =(x^2-9)(x^2-x-2)

Since the value of i^2=-1

            =x^2(x^2-x-2)-9(x^2-x-2)

            =x^4-x^3-2x^2-9x^2+9x+18

            =x^4-x^3-11x^2+9x+18

Simplest polynomial function is x^4-x^3-11x^2+9x+18.

What is the minimum value for g(x)=x^2-10x+16? Enter your answer in the box.
Anna71 [15]

Answer:

- 9

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

To obtain this form use the method of completing the square

add/subtract (half the coefficient of the x- term)² to x² - 10x

g(x) = x² - 10x + (- 5)² - (- 5)² + 16

      = x² - 10x + 25 - 25 + 16

     = (x - 5)² - 9 ← in vertex form

vertex = (5, - 9), hence

minimum value = - 9
