The left sum would be f0+f1+f2+f3
The right sum would be f1+f2+f3+f4
The trapezoidal rule value is:
(f0+f1)/2 + (f1+f2)/2+(f2+f3)/2 +(f3+f4)/2
This would put the trapezoidal rule in the middle , which makes the answer:
Lower sum < Trapezoidal rule Value < Upper sum
Replace the range for f(x)
So...
0=4-2x
x=2
4=4-2x
x=0
8=4-2x
x=-2
Solve!
These are your domains!
Step-by-step explanation:
47-4x<7
-4x<7-47
-4x<-40
x>(40÷4)
x>10
Answer:
you put two of the equations together and then the last one there you just automatically added on
Step-by-step explanation:
4x-7y=-28
25xy
892.48
You have to subtract he given numbers.
