Answer 1

Answer: $f(-2)=-6$

Step-by-step explanation:

For this exercise it is important to remember the multiplication of signs:

$(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-$

You have the following function provided in the exercise, which represents the path traveled:

$f(x) = 4x + 2$

In order to find the value of $f(-2)$ you can follow these steps:

1. You need to substitute $x=-2$ into the function, then:

$f(-2) = 4(-2)+ 2$

2. Finally you must evaluate. Then you get:

$f(-2) =-8+ 2\\\\f(-2)=-6$
