Answer 1

. X ) to X- f(x)=4 Divide the such that internal LI, OJ into n=2 Sabint errel [xing xi]; i=1,2 length of each subinternal is x = 9-1 And no , % = %+ 0x = 1+ 7 = 92 = , + DX = 9 + 7 / old on 16 - 8 2 11 2 .. Midpoint of [xo, x, ] = [!, ?J is to = 1+q 12 - $ Midpoint of [x,, 4x) = (, pg is t, - 470 then by Midpoint sule, the approximate cender the care f(x) = 1/2 from x=1 x = 0, is given by to=144 t=28 -25 to Are ar Ax [ f(t) +f14)] IF("x) + f(23)] 1 / 2 1 1 2 3 4 *F9/ *2=8 1 / 2 1 4 4 + 1/5 100444 275 - 7 ) L 1008 Soy ) 550 275 Area Ň Soy the desired approxioration. 275 B. soy is the 275 correct option.
