Step-by-step explanation:
f(x) = x² + 1, where x >= 0.
Let y be f(x).
=> y = x² + 1
=> x² = y - 1
=> x = √(y - 1) because x is non-negative.
Hence f^-1(x) = √(x - 1), where x >= 1.
It is 3 because you take 5 times 3 and it equals 15
Answer:
i pretty sure its 6
8x
Step-by-step explanation:
i did the research
The chances would be (if you cant get duplicates)
1/6
1/5
1/4
If you want the states in order
You multiply them together
6 x 5 x 4 = 1/120 chance to get them in that order
