Xy^16 / 4
I don't really know how to explain it, but this is the answer
Given
- f(n) values for n=1,2,3,4
- possible candidates for the function
Solution:
Method: Evaluate some of the values, for each function. A function with ANY value not matching the given f(n) values will be rejected.
N=1, f(n)=4
f(1)=4-3(1-1)=4
f(1)=4+3^(1+1)=4+3^2=4+9=13 ≠ 4 [rejected]
f(1)=4(3^(n-1))=4(3^0)=4
f(1)=3(4^(n-1))=3(4^0)=3*1=3 [rejected]
N=2, f(n)=12
f(1)=4-3(2-1)=4-3(1)=1 ≠ 12 [rejected]
[rejected]
f(1)=4(3^(2-1)=4*3^1=4*3=12
[rejected]
Will need to check one more to be sure
N=3, f(n)=3
[rejected]
[rejected]
f(3)=4(3^(n-1))=4(3^(3-1))=4(3^2)=4*9=36 [Good]
[rejected]
Solution: f(n)=4(3^(n-1))
Step-by-step explanation:
So we go backwards, since we have x= 1/2 , 7
Now we have to foil to get the quadratic
We must simplify the terms
Our final result comes out to be
Answer:
|-8|=8
|10|=10
Step-by-step explanation:
any negative number between the two slashes '||' equals to always a positive number
and a positive number between the two slashes '||' remains the same
Answer:
x=1
Step-by-step explanation:
Subtract
18
from both sides
Simplify
3
Subtract
2x
from both sides
