NEED HELP ASAP !!!

Step-by-step explanation:

In order to know which equation we need to consider, we have to check the value of x. If x is negative, we will replace x in the first equation and if x is positive or null we will replace it in the second equation.

(a) x=-4 so x is negative. We use the first equation and we have

(b)x=2 and is positive so we use the second equation  . The result is

(c)x=0 In this case the function is defined by the second equation . So

(d)Here we have both case in the same calcul. We need to calculate the fonction values of each one and then make the sum.

With , x=-100 and is negative so we use the first equation   and we have .

With , x=100 ans is positive so we use the second equation and get .

We add them to get the result :

(e)

(f)

(g)
