Answer:
![4](https://tex.z-dn.net/?f=4)
Step-by-step explanation:
Given: ![f(x)=4x-2](https://tex.z-dn.net/?f=f%28x%29%3D4x-2)
To find: average rate of change of the function
over the interval
and ![x=2](https://tex.z-dn.net/?f=x%3D2)
Solution:
Take ![a=-1,\,b=2](https://tex.z-dn.net/?f=a%3D-1%2C%5C%2Cb%3D2)
Find ![f(a),\,f(b)](https://tex.z-dn.net/?f=f%28a%29%2C%5C%2Cf%28b%29)
![f(a)=f(-1)\\=4(-1)-2\\=-4-2\\=-6\\\\f(b)=f(2)\\=4(2)-2\\=8-2\\=6](https://tex.z-dn.net/?f=f%28a%29%3Df%28-1%29%5C%5C%3D4%28-1%29-2%5C%5C%3D-4-2%5C%5C%3D-6%5C%5C%5C%5Cf%28b%29%3Df%282%29%5C%5C%3D4%282%29-2%5C%5C%3D8-2%5C%5C%3D6)
Average rate of change of the function ![=\frac{f(b)-f(a)}{b-a}](https://tex.z-dn.net/?f=%3D%5Cfrac%7Bf%28b%29-f%28a%29%7D%7Bb-a%7D)
![=\frac{f(2)-f(-1)}{2-(-1)}\\\\=\frac{6-(-6)}{3} \\\\=\frac{12}{3}\\\\=4](https://tex.z-dn.net/?f=%3D%5Cfrac%7Bf%282%29-f%28-1%29%7D%7B2-%28-1%29%7D%5C%5C%5C%5C%3D%5Cfrac%7B6-%28-6%29%7D%7B3%7D%20%5C%5C%5C%5C%3D%5Cfrac%7B12%7D%7B3%7D%5C%5C%5C%5C%3D4)
Answer:
Vertical Line test
Step-by-step explanation:
If you can put a vertical line anywhere on the graph, and it doesn't touch more than one point, then it's a function. A function means there are no repeated x values.
