What is the domain and range of f(x)=x

Mathematics

The domain is all real numbers. The range is all real numbers.

The only thing that restricts the domain of an equation is when we are dividing by 0 or have a negative under the square root. Since there is no division sign or square root, we no there is no domain restrictions.

Also, since the range is the exact same as the domain (since f(x) is equal to x), we know the range also have no restrictions.

Anyone know how to do area or volume? Any help will do! thanks
exis [7]

Answer:

Volume: x(x+6)(x+2) Area: x^{2} + 8x +12

Step-by-step explanation:

Volume Explanation:

To find the volume of a 3d figure, we must multiply the length, width, and the height. Therefore we multiply (x)(x+6)(x+2)= x^{3} + 8x^{2} + 12x. Simplify this equation and we will get x(x+6)(x+2) for the formula to find the volume of the 3D figure.

Area:

To find the area of a 2D figure, we must multiply length x height. Therefore, we multiply the equations (x+6)(x+2)= x^{2} + 2x + 6x +12 to get a final answer of x^{2} +8x +12.  This will be the formula when you find the area of the 2D figure in question.

The two polygons above are similar. The scale factor of the smaller polygon to the larger polygon is 3. The area of the smaller
Softa [21]
You would think it was 3 * 12 = 36. Not so. All polygons have to be broken down into some figure that will give 2 dimensions that are at right angles to each other. That would mean that
d1 * d2 = Area for the small polygon
3d1 * 3d2 = area of the larger polygon

What that means is that the area of the larger one is 9 times the smaller one.
Area large = 12 * 9 = 108 square units. <<<<< answer.

If you find this hard to be leave try it with a square.
Suppose you have a square (the small one) that is 3 cm by 3 cm
The small one has an area of 3*3 cm^2 = 9 cm

Now you have another square that is 3 times larger. That means that each side is 3*3 = 9
So s = 9
Area = s^2
Area = 9^2 = 81 cm^2
81 is 9 times larger than 9 just as you would think.
