3 3 Astudent was asked to find / 2:1: (2:2 6) dcc. 1 Check the student's work beLow and determine whether or not it is correct. If not correct, explain [in detail) what mistake was made. 3 3 f 231(332 6) 30h: 2 f 15st _ 1 l u) = us which makes F(u) = EH4 3 1 4 1 4 50,]:1u3dx=F{3)F(1] =19} 1(1) =20 r'_'\ correct '3' incorrect ExpLain: 2 9x2 A student was asked to find / d;n. 0 3m3 + 2 Check the student's work beLow and determine whether or not it is correct. If not correct, explain [in detail) what mistake was made. If we Let n = 3:33 + 2, then do 2 ngdat. So: 2 2 26 9 1 / Ldm =f du = F(2) 13(2) 0 3333 'i 2 2 u 1 26 and FEED} F(2) = 13 1 '5 f_'\ correct '3' incorrect Explain: A student was asked to find dx. 1 22 Check the student's work below and determine whether or not it is correct. If not correct, explain (in detail) what mistake was made. f(z) = x 2-2+1 The antiderivative is F(x) = -2+1 83 So , dx = F(5) - F( -1) = = = O correct O incorrect Explain
