Question

. During the Grinch's engine test, if the path traveled is represented by the

function f(x) = 4x + 2. what is the value of f(-2), corresponding to "Hit
Here"?

Answer 1

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

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`
