Likely a really easy answer and I'm just panicking but if you could help me out with: Steps would be nice. Answer should be 127/6 but i keep getting 55/6

Haven't done maths in a while but i got 127/6 Merged Post: Intergrate 5x from 0 to 1 = 2.5 Ignore -1001 at x = 1 Intergrate 2 from 1 to 4 = 6 Ignore 343 at x = 4 Intergrate square root x from 4 to 9 = 12 and 2/3 Add all that up and i got 21 and 1/6 = 127/6
