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
Solutions
⇒ 5/10
5/10 is not in simplest form
1) The Greatest Common Factor of 5 and 10 is 5
5 ÷ 5 = 1
10 ÷ 5 = 2
2) simplify
5/10 in simplest form is 1/2
10≤n<100
So the number of two digit numbers is 99-10+1=90
The only combinations that sum to 5 are 14, 23, 32, 41, 50 so
P(sum=5)=5/90
P(sum=5)=1/18
Answer: 1/6
Step-by-step explanation:
just simplify 2/12 to 1/6
2/12 both divided by 2
Yes because fraction wise the denominator that is the smallest is greater. At least that is what I learned
