Linear means the highest exponent on the placholder is 1
it is also just a straight line
y=|x| is like y=(√x)², it is 2 straight lines
B. y=x², exponent is 2 so no
C. y=-3x³, exponent is 3, so no
D. y=1/4x, yep
D is the answer
        
                    
             
        
        
        
3x +7x+x+x should be your answer
        
                    
             
        
        
        
The domain is y >=0. Domain is the possible x values
        
             
        
        
        
Answer:
4 1/6
