Determine the domain of the following graph:
Sati [7]

Answer:

x is greater than or equal to -7 but less than 9.

Step-by-step explanation:

Find the lowest and higest points on the graph.

Remember the domain is on the x - axis.

The lowest point on the graph is -7, but the dot is filled in so it must be equal to it.

The next step is that the graph is getting larger so it is greater than or equal to.

On the other side of the graph do the same but it is less than not equal because the dot is open.

NEED HELP BEING TIMED
Firlakuza [10]

Answer:

Yes.

Step-by-step explanation:

This problem has some different steps, so lets break it down:

Ed has 12 glasses of punch with 120 milliliters of liquid contained each.

Therefore, Ed has 12 * 120 milliliters of liquid:

12 * 120 = 1440

Now, we need to convert to liters, because that is what Ed's possible answer unit is in. Since there are 1000 milliliters in a liter, we will divide 1440 by 1000.

1400 \: \div\: 1000 = 1.44.

Thusly, Ed is correct and the answer is  \boxed{\text{Yes}}}.

Hope this helps! Have a nice day! ((:

What are the roots of the quadratic equation X² + 4X + 4. How many roots are there.
kogti [31]
If we set the equation equal to 0, we can factor it to find its roots:

x² + 4x + 4 = 0
(x + 2)(x + 2) = 0
x = -2

This graph has one root, a double root, at -2.  This means that a single point, which must be the vertex of the parabola, touches the x-axis at (-2, 0)
