Answer:
C: x = 7
Step-by-step explanation:
The easiest way to do this is to simply try all of the x-vales given as options.
Option 1: x = -1
Since  , we'll use the first equation.
, we'll use the first equation.

As we can see, g(-1) is not -4.
Option 2: x = 3
Since  , we'll use the 2nd equation.
, we'll use the 2nd equation.

Not -4.
Option 3: x = 7
Since  , we'll use the 3rd equation.
, we'll use the 3rd equation.

Tada! We have found a number such that g(x) = -4, it is 7. Since we only need to find a number, not all numbers, we don't have to check the last option. However, if you're curious:
Option 4: x = 4
Since  (less than <em>or equal to</em>), we'll use the 3rd equation.
 (less than <em>or equal to</em>), we'll use the 3rd equation.

 
        
             
        
        
        
Answer:
x > 1
Step-by-step explanation:
2x+5>7
move constant to right
2x>5-7
subtract 7 and 5
2x>2
divide both sides
x > 1
