Explanation:
For this exercise it is important to remember the multiplication of signs:
![(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-](https://img.qammunity.org/2020/formulas/mathematics/middle-school/r76df95ankxjidecek21t2m1fzsoe41xde.png)
You have the following function provided in the exercise, which represents the path traveled:
![f(x) = 4x + 2](https://img.qammunity.org/2020/formulas/mathematics/high-school/aa6l9t5l63pfysrkjije871oxtu1gpeejx.png)
In order to find the value of
you can follow these steps:
1. You need to substitute
into the function, then:
![f(-2) = 4(-2)+ 2](https://img.qammunity.org/2020/formulas/mathematics/high-school/92wjd03zzhxlwnhppruxrynw2jyynjkm34.png)
2. Finally you must evaluate. Then you get:
![f(-2) =-8+ 2\\\\f(-2)=-6](https://img.qammunity.org/2020/formulas/mathematics/high-school/6wstf0cv9gbbrjuvhpfg8b6yzfv5ualllf.png)
