Question

Please help me I have had help with the 3 one but I can not reproduce it. Thank you to who helps me.

Answer 1

Note that:

`\int f(x) \text{ } dx=-e^(-x/5)+C`

Part (b)

`\int^(1)_(0) f(x) \text{ } dx =-e^(-1/5)+e^(0) \approx 0.1813`

Part (c)

`\int^(\infty)_(0) f(x) \text{ } dx =1.0000`

Part (e)

`\int^(6)_(1) f(x) \text{ } dx \approx 0.5175`
