![{2}^{ - 1}](https://tex.z-dn.net/?f=%7B2%7D%5E%7B%20-%201%7D%20)
Step-by-step explanation:
![{2}^{2} \times \frac{2}{ {2}^{4} } = \frac{2}{ {2}^{2} } = \frac{1}{2} = {2}^{ - 1}](https://tex.z-dn.net/?f=%7B2%7D%5E%7B2%7D%20%20%5Ctimes%20%20%5Cfrac%7B2%7D%7B%20%7B2%7D%5E%7B4%7D%20%7D%20%20%3D%20%20%5Cfrac%7B2%7D%7B%20%7B2%7D%5E%7B2%7D%20%7D%20%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%3D%20%20%7B2%7D%5E%7B%20-%201%7D%20)

Step-by-step explanation:
Good luck
If
, then
![f(x+h)=4-(x+h)^2=4-(x^2+2xh+h^2)=4-x^2-2xh-h^2](https://tex.z-dn.net/?f=f%28x%2Bh%29%3D4-%28x%2Bh%29%5E2%3D4-%28x%5E2%2B2xh%2Bh%5E2%29%3D4-x%5E2-2xh-h%5E2)
So
![\dfrac{f(x+h)-f(x)}h=\dfrac{(4-x^2-2xh-h^2)-(4-x^2)}h=-\dfrac{2xh+h^2}h](https://tex.z-dn.net/?f=%5Cdfrac%7Bf%28x%2Bh%29-f%28x%29%7Dh%3D%5Cdfrac%7B%284-x%5E2-2xh-h%5E2%29-%284-x%5E2%29%7Dh%3D-%5Cdfrac%7B2xh%2Bh%5E2%7Dh)
Then for
, we can cancel common terms:
![\dfrac{f(x+h)-f(x)}h=-2x+h](https://tex.z-dn.net/?f=%5Cdfrac%7Bf%28x%2Bh%29-f%28x%29%7Dh%3D-2x%2Bh)
