I’m not sure about the wording of the question, but wouldn’t it be all real numbers?
        
                    
             
        
        
        
Step-by-step explanation:
This is confusing, what does g(x) equal? There's a bunch of random numbers there. I'll just assume.
They stated that f(x) needs to exceed g(x), so make an inequality plugging in the values

You see, function f(x) needs to be higher than function g(x)
Subtract 7x from both sides to get:

Divide both sides by -4, when you divide by a negative number the signs switch so it is now less than.
x < -1.5
And obviously that's not an answer up there, so you made a mistake stating the values of the functions
