Answer:
f−1(f(x)) = f(f−1(x)) = x
Step-by-step explanation:
Follow this simple example using the function f(x) = x + 2
f(x) = x + 2
NOw we find the inverse function f^(1)(x).
y = x + 2
x = y + 2
y = x - 2
f^(-1)(x) = x - 2
The inverse function is f^(-1)(x) = x - 2
Now we do the two compositions of functions:
f^(-1)(f(x)) = x + 2 - 2 = x
f(f^(-1)(x)) = x - 2 + 2 = x
Both are equal to x.
Answer: f−1(f(x)) = f(f−1(x)) = x
Answer:
6 chores
Step-by-step explanation:
ok so,
4 hours=240minutes
2/3of an hour= 60×2/3
=40 minutes
so since one chore needs 40 minutes, then:
40/240= 6
so in 240 minutes/4 hours, Spencer can do 6 chores.
Answer:
55.83
Step-by-step explanation:
Divide the number of pounds by 2.2046 to use the standard equation.
False. Since the probability of one side of the coin is 3/10, the other must be 7/10.
