Given:

There are given that the zeroes and degrees of the polynomial:

$\begin{gathered} \text{zeros:}-2,2,4 \\ \text{Degres:}3 \end{gathered}$

Explanation:

From the concept of a polynomial:

A polynomial has a as zero if and only if (x -a) is a factor of the polynomial.

Then,

From the given polynomial:

$f(x)=(x+2)(x-2)(x-4)$

Then,

$\begin{gathered} f(x)=(x+2)(x-2)(x-4) \\ f(x)=(x^2-2x+2x-4)(x-4) \\ f(x)=(x^2-4)(x-4) \\ f(x)=x^3-4x^2-4x+16 \end{gathered}$

Final answer:

Hence, the polynomial is shown below:

$f(x)=x^3-4x^2-4x+16$

The line through (6,-6) with slope 1/2 in point-slope form ?

aleksandrvk [35]

Answer: $y + 6 = \frac{1}{2}(x - 6)$

Step-by-step explanation:

Point-slope formula: $y - y1 = m(x - x1)$

Plug in the numbers: $y - -6 = \frac{1}{2}(x-6)$

Clear the double negatives: $y + 6 = \frac{1}{2}(x - 6)$
