The statement that -6 is in the domain of f(g(x)) is true
<h3>Complete question</h3>
If f(x) = -2x + 8 and g(x) =
, which statement is true?
- -6 is in the domain of f(g(x))
- -6 is not in the domain of f(g(x))
<h3>How to determine the true statement?</h3>
We have:
f(x) = -2x + 8

Start by calculating the function f(g(x)) using:
f(g(x)) = -2g(x) + 8
Substitute 

Set the radicand to at least 0

Subtract 9 from both sides

This means that the domain of f(g(x)) are real numbers greater than or equal to -9. i.e. -9, -8, -7, -6, ...........
Hence, the statement that -6 is in the domain of f(g(x)) is true

Did you mean 36/12? If so the answer would be 3/1 or 3.
The average speed can be obtained by the formula:

If a boat travels 36 miles in 1.5 hours ans then in 14 miles in 0.75 hour, then find:
- total distance is 36+14=50 miles;
- total time: 1.5+0.75=2.25 hours.
Therefore,
miles per hour.
Answer:
miles per hour.
