Answer:
x= -7/2
Step-by-step explanation:
Let's use 304,900,000 as an example.
In scientific notation it is 3.049 x 10^8
When converting to scientific notation, just drop any zeros at the end of the number and put the decimal place after the first digit. Then for the power on the 10, count all the digits (including zeros). In our example there are 8 digits after the 3 so we raise 10 to the 8th power.
Now let's look at small numbers. For example, 0.0000718
If the number is between 0 and 1, we will raise the 10 to a negative power. In this case the answer is 7.18 x 10^-5.
What you do to find the power is move the decimal point over so that there is one digit in front. Just like we did with the first example. Count how many places the decimal moved and use it for the power.
Hopefully this helps. Let me know if you need further explanation :)

Answer:
10. Expanded vertically by 3, shifted left 2 and up 4.
11. Shifted right 6 and up 7.
Step-by-step explanation:
This sort of question involves matching patterns. You need to know what the various transformations look like, and what that means for a specific parent function.
Here are the transformations used in this problem:
- f(x -a) . . . . shift f(x) to the right by "a" units
- f(x) +a . . . . shift f(x) up by "a" units
- a·f(x) . . . . . vertically scale f(x) by a factor of "a"
For these problems, the parent function is f(x) = 1/x.

10. The multiplier of 3 in the numerator (3/x) means the function has been scaled vertically (expanded) by a factor of 3.
The replacement of x with x+2 means the function has been shifted to the right by -2 units. That is the same as shifted left 2 units.
The addition of 4 to the function value means the function has been shifted up by 4 units.
__
11. We note the numerator is still 1, so there is no vertical expansion. The replacement of x with x-6 means a right shift by 6 units. The addition of 7 to the function value means a shift up by 7 units.
