Answer:
8x +4h
Step-by-step explanation:
![\dfrac{f(x+h)-f(x)}{h}=\dfrac{(4(x+h)^2-8)-(4x^2-8)}{h}\\\\=\dfrac{(4x^2 +8xh+4h^2)-(4x^2-8)}{h}=\dfrac{8xh+4h^2}{h}\\\\=\boxed{8x+4h}](https://tex.z-dn.net/?f=%5Cdfrac%7Bf%28x%2Bh%29-f%28x%29%7D%7Bh%7D%3D%5Cdfrac%7B%284%28x%2Bh%29%5E2-8%29-%284x%5E2-8%29%7D%7Bh%7D%5C%5C%5C%5C%3D%5Cdfrac%7B%284x%5E2%20%2B8xh%2B4h%5E2%29-%284x%5E2-8%29%7D%7Bh%7D%3D%5Cdfrac%7B8xh%2B4h%5E2%7D%7Bh%7D%5C%5C%5C%5C%3D%5Cboxed%7B8x%2B4h%7D)
