Answer 1

Given function:

`f(x) = -8x + 1.`

Let's find the difference quotient:

`(f(x+h)-f(x))/(h)\\\\= ([-8(x+h)+1] - (-8x + 1))/(h)\\\\= (-8x-8h+1+8x-1)/(h)\\\\ = (-8h)/(h)\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,(h\\eq 0)\\\\= -8.`

Answer 2

• -8

Explanation:

`\bf \cfrac{f(x + h) - f(x)}{h}`

`\bf f(x) -8x + 1`

`\bf f(x+h) = -8x-8h+1`

`\bf \cfrac{ - 8x - 8h + 1 + 8x - 1}{h}`

`\bf =\cfrac{ - 8h}{h}`

`\bf = - 8`
