I’m pretty sure your counting by 3’s because It’s goes 9,3 . However it might be in the negatives
        
             
        
        
        
No x-intercept/zero
Step by step
To find x-intercept/zero, substitute f(x)=0
F(x)=-20
0=-20
The statement is false for any value of 
X=0
Since there is no solution for f(x)=0, there is no -intercept/Zero
Your welcome:)
        
             
        
        
        
Do you have answer choices? if not that’s okay but I did do the work and would be able to reply with the picture!
        
             
        
        
        
Answer:  0
To find this answer, we replace x with 0 in the g(x) function
g(x) = -2x
g(0) = -2*0
g(0) = 0
