Answer:
31
Explanation:
The function given in this problem is described by the expression
![f(x)=3x+1](https://img.qammunity.org/2021/formulas/mathematics/high-school/h3l419gkl324c54ywuscukrtzaxqbt8278.png)
In this problem, we want to find
![f(10)](https://img.qammunity.org/2021/formulas/mathematics/high-school/jtgjqa5guehub1v2vhi15z2bazqhdmj6t1.png)
Which means that we want to evaluate the function when the value of x is 10, so when
![x=10](https://img.qammunity.org/2021/formulas/mathematics/middle-school/yveq4wkntm80fiuxnqfce6qwd476ocdd80.png)
To solve the problem, we just need to substitute x = 10 into the expression of f(x). By doing so, we find:
![f(10)=3\cdot 10 +1 = 30+1 = 31](https://img.qammunity.org/2021/formulas/mathematics/high-school/xje32au7gh020wvr6sv627m95u6eurso7k.png)
Therefore, the correct option is
31
