StartFraction 1 Over negative StartRoot 8 x + h minus 35 EndRoot + StartRoot 3 x minus 35 EndRoot EndFraction; h ≠ 0
StartFraction 1 Over negative StartRoot 8 x + h minus 35 EndRoot minus StartRoot 3 x minus 35 EndRoot EndFraction; h ≠ 0
StartFraction 8 Over negative StartRoot 8 x + h minus 35 EndRoot + StartRoot 3 x minus 35 EndRoot EndFraction; h ≠ 0
StartFraction 8 Over negative StartRoot 8 x + h minus 35 EndRoot minus StartRoot 3 x minus 35 EndRoot EndFraction; h ≠ 0

Answer 2

The option fourth represents the difference quotient of the function f(x) option fourth is correct.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

$\rm f(x) = - \sqrt{8x-35}$

$\rm f(x+h) = - \sqrt{8(x+h)-35}\\\\\rm f(x+h) = - \sqrt{8x+8h-35}$

Difference quotient:

$\rm = \dfrac{f(x+h)-f(x)}{h}$

$\rm = \dfrac{- \sqrt{8x+8h-35}+ \sqrt{8x-35}}{h}$

After rationalization;

$\rm = \dfrac{- \sqrt{8x+8h-35}+ \sqrt{8x-35}}{h} \times \dfrac{ \sqrt{8x+8h-35}+ \sqrt{8x-35}}{\sqrt{8x+8h-35}+ \sqrt{8x-35}}$

$\rm = \dfrac{8}{-\sqrt{8x+8h-35}- \sqrt{8x-35} }$     , h ≠ 0

Thus, the option fourth represents the difference quotient of the function f(x) option fourth is correct.
