Solve for x from the above problem: 3x = 12 - X*
O
X = 4
O x= 3
O X=-3
Ox=4

Answer 3 times 4 =12 12-3=9  distributive

Step-by-step explanation:

3

Step-by-step explanation:

This one has a similar concept to the other one solved here.  

Basically we follow the piece wise function.

Explanation of piece wise function

         _

        |  -x + 7,        x ≤ 1

f(x) = |  x³ - 5,       -1 < x < 2

        |  3 ,             x ≥ 2

         _

When x in f(x) is less than or equal to 1 than f(x) = -x + 7

When x in f(x) is greater than -1 but less than 2 than f(x) = x³ - 5

When x in f(x) is greater than or equal to 2 than f(x) = 3

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Now lets look back at the question

We want to find f(5,000,000,000,000,000)

Looking at the piece wise function we see that the x in f(x) (5,000,000,000,000,000) follows x ≥ 2 as 5,000,000,000,000,000 is greater than 2. When x is greater than or equal to 2, f(x) = 3, hence f(5,000,000,000,000,000) = 3
