Find a polynomial function of degree 3 with real coefficients that has the given zeros. -1, 2, -8 The Polynomial function is f(x

lakkis [162]

The zeros are -8, -1, 2, so you can write the function as f(x)=(x-(-8))(x-(-1))(x-2)=(x+8)(x+1)(x-2).

Expand:
$(x+8)(x+1)(x-2)= \\
(x^2+x+8x+8)(x-2)= \\
(x^2+9x+8)(x-2)= \\
x^3-2x^2+9x^2-18x+8x-16= \\
x^3+7x^2-10x-16$

The function is f(x)=x³+7x²-10x-16.
The missing value is 7.

. Write an equation of the line that passes through the given points use point

Damm [24]

Answer:

$y = \frac{1}{3}x+\frac{1}{3}$

Step-by-step explanation:

First, we need to figure out a linear equation. When given two points - $(x_{1}, y_{1})$ and $(x_{2}, y_{2})$ - first subtract $y_{1}$ from $y_{2}$ and and $x_{1}$ from $x_{2}$ . So in your situation, it will be $2-1$ and $5-2$ . That equals $1$ and $3$ , so your slope (how much the line moves up/down per unit) will be $\frac{1}{3} x$ .
