Step 1

We have that a=−1, b=2, n=6 help_outlineImage Transcriptionclose2 (1) 1 6 subintervals of length Ar 2 Divide the interval 1,2 into n -[+-130 036-11물이 b ,2 2 a= 2 fullscreen
Step 2

Then we evaluate the function ... help_outlineImage Transcriptionclosef(o)= f(a)= f(-1) = 5 = 5 23 = 5,75 4 f(e)3 f(x2)= f(0) 6 = 6 23 5.75 4 f() f (x4)= f(1) 5 = 5 15 3.75 4 f (ars)= f = 2 fullscreen
