No because u would multiply to get a common denominator and it would be 4/6 5/6
        
                    
             
        
        
        
Answer:
All Real Number greater than 0 or 
(0, positive infinity)
Step-by-step explanation:
The range is all possible y values of a function. We can tell a range by looking at the lowest y vaule then going to the highest possible y value.
Look at the graph. There is a open circle at y=0. So this means we are not going to include 0 in our function. The graph approaches f(x) to positive Infinity so our highest y value is Infinity. 
So we know that the function y values  cannot be zero and it must be positive. So our range is 
All Real Number greater than 0. Or
(0, positive infinity)
 
        
             
        
        
        
Answer:
The cost of 250 g carrots is €0.45.
Step-by-step explanation:
Given that,
Cost of carrots is €1.80 per kg
We need to find the cost of 250 g of carrots.
1 kg cost = €1.80
We know that, 250 gram = 0.25 kg
0.25 kg cost = €1.80 × 0.25
= €0.45
So, the cost of 250 g carrots is €0.45.
