The value of the function is 6
Step-by-step explanation:
The function that we have in this problem is
![f(x)=\left \{ {{3x^2+1}, -4](https://tex.z-dn.net/?f=f%28x%29%3D%5Cleft%20%5C%7B%20%7B%7B3x%5E2%2B1%7D%2C%20-4%3Cx%3C6%20%5Catop%20%7B6%7D%2C%206%5Cleq%20x%20%3C9%7D%20%5Cright.)
This means that:
when x is between -4 (excluded) and 6 (excluded), the value of the function is ![3x^1+2](https://tex.z-dn.net/?f=3x%5E1%2B2)
when x is between 6 (included) and 9 (excluded), the value of the function is 6
In this problem, we are asked to evaluate f(x) when x = 6. Therefore, we are in the second case: therefore, the value of the function is 6,
![f(x)=6](https://tex.z-dn.net/?f=f%28x%29%3D6)
