Question

Questions 3 and 4 please I would like to learn how to solve these

Answer 1

Given:

`f(x)=x+6`

Assuming

`h\\e0`

Compute:

`\begin{gathered} (f(x+h)-f(x))/(h)= \\ =((x+6+h)-(x+6))/(h) \end{gathered}`
`\begin{gathered} =(x+6+h-x-6)/(h) \\ =(h)/(h) \\ =1 \end{gathered}`

Hence, the required answer is :1
