1 * 60 * 60 = 3600 (seconds in 1 hour)
3600 * 6 = 21600 (seconds in 6 hours)
3600 * 0.4 = 1440 (seconds in 0.4 hour)
21600 + 1440 = 23040 (6 hours + 0.4 hours)
your answer is 23040

Answer:
Its 3
Step-by-step explanation:
i took the test
If y = f(x), then f⁻¹(y) = x.
We have f(x) = 2x + 2, so that f(x) = 4 when
2x + 2 = 4
2x = 2
x = 1
So we know f(1) = 4.
Then this means 1 = f⁻¹(4).
