Answer:
The y intercept would be -4.
Plot as (0, - 4)
They would have 2 because is it 10:1 just double it to be 20:2
-6r+5
the two like terms are the ones with R. combine -4r and -2r to get -6r
If order doesn't matter then the number of possible choices is:
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
