For the first question
1/x-3, x cannot equal +3. As that would make the denominator 0.
For the second question.
Substitute f(x) into g(x) to get:
x^2 - 3
The second number after the decimal is the hundredths place. To round to that place, you look at the number after it. In this case 6 is the hundredths place and 5 is the number after it. If the number after it is 5 or higher, the hundredths place number increases by 1, if it is less than 5 the hundredths place number doesn't change. So the answer is 8.47.
