$x^3+8x\not =0\\ x(x^2+8)\not =0$

$x^2+8>0$ for any x, so only $x\not =0$

$D_f:x\in(-\infty,0)\cup(0,\infty)$

Step-by-step explanation:

To complete the square take the coefficient of the x term

Divide by 2

4/2 =2

Square it

2^2 =4

Add it to both sides of the equation

x^2 +4x+4 = 4

What is the inequality?

vlabodo [156]

Answer:

y < 0.25x + 4

Step-by-step explanation:

The dotted line indicates that the inequality is either a greater than(>) or less than(<). This is because the answer does include the set of points along the line.

We are looking to find an inequality such that any point below that is considered a solution. Thus, after finding the line's equation in slope-intercept form, we can replace the = with <.

Solving for the line:

Take any 2 points and determine the slope. I used (-8,2) and (0,4). The slope using $\frac{y_2-y_1}{x_2-x_1}$ results in $\frac{1}{4}$ or 0.25. As we can see visually from the graph, the y-intercept is (0,4). Thus, the equation of the line is y = 0.25x + 4.

Now all we do is replace the = with the < and we have our answer:

y < 0.25x + 4
