Answer: [tex]f(-2)=-6[/tex]
Step-by-step explanation:
For this exercise it is important to remember the multiplication of signs:
[tex](+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-[/tex]
You have the following function provided in the exercise, which represents the path traveled:
[tex]f(x) = 4x + 2[/tex]
In order to find the value of [tex]f(-2)[/tex] you can follow these steps:
1. You need to substitute [tex]x=-2[/tex] into the function, then:
[tex]f(-2) = 4(-2)+ 2[/tex]
2. Finally you must evaluate. Then you get:
[tex]f(-2) =-8+ 2\\\\f(-2)=-6[/tex]
