Answer:
The best answer is C.
Step-by-step explanation:
Answer:
Step-by-step explanation:
g(t)=t^2 - t
f(x) = (1 + x)
g(f(x)) = f(x)^2 - f(x)
g(f(x)) = (x + 1)^2 - x - 1
g(f(0)) = (0 +1)^2 - x - 1
g(f(0)) = 1 - 1 - 1 = -1
================================
f(x) = 1 + x
f(g(t)) = 1 + g(t)
f(g(t)) = 1 + t^2 - t
f(g(0)) = 1 + 0 - 0
f(g(0)) = 1
The answer I'm getting is 0.
Answer:
I thinks it A or D
Step-by-step explanation:
Yea A Or D is our answer
Answer:
1. We will prove by induction over n, that for an integer n, 
is divisible by 2.
For n= 1, 
and 
. Then for n=1 the property is satisfied.
Suppose as induction hypothesis that for an integer n, is divisible by 2, that is, 
.
Let's see with n+1.
But,
,
by induction hypothesis
This shows that for n+1 the property is satisfied, then we can conclude that that for an integer n, is divisible by 2.
2. Let 
sets. By definition,
Then, each element of A is in 
, that is, 
.
