1. 3x + 5 [2,5]
= (3(5) + 5) – (3(2) + 5)
= 20 – 11
= 9

2. 6x -5 [0,3]= (6(3) – 5) – (6(0) -5)
= 4 – (-5)
= 9

3. 3/5x + 5/2 [-4,4]
= (3/5(4) + 5/2) – (3/5(-4) + 5/2)
=49/10 – 1/10
= 24/5

4. 4x2 + 3x + 2[0,2]
= (4(2)2 + 3(2) + 2) – (4(0)2 + 3(0) + 2)
= 24 – 2
= 22

5. 2/3x2 - 5/4x + 2 [3,6]
= (2/3(6)2 – 5/4(6) + 2) – 2/3(3)2 – 5/4(3) + 2)
=37/2 – 17/4
= 57/4

1. 3x + 2 de 2 a 3
= (81/2 + 6) – (6 + 4)
= 93/2 – 10 = 73/2
2. 4x2/2 + 25x de 0 a 5
= 50 + 125
= 175

3.2x3/3 + 3x2/2 -5x de 3 a 8
= (1024/3 + 96 - 40) – (18 + 27/2 – 15)
= 1192/3 – 33/2
= 2285/6

4. 2x5/5 – 3x3/3 +5x2/2 – 3x de 0 a 4
= (2048/5 –27 + 40 – 12)
= 20486

5. 15x6/6 – 6x4/4 + 2x2/2 – 6x de -5 a -2
= (160 - 24 + 4 + 12) - (234375/6 – 3750/4 +25 + 30)
= 152 – 38180
= -38028
