Answer:
It will equally 2 because you need to change the 3 into a 9 because you can't add fractions without having the same common demometer 
Step-by-step explanation:
 
        
             
        
        
        
A) For f(-1) we use the part of the piecewise function for when x < 0 because -1 < 0. Plug in -1 for x:
2(-1) + 3 = 1
b) For f(0), we use the part for when x 

 0.
4(0) + 5 = 5
c) For f(2) we use the part for when x 

 0.
4(2) + 5 = 13
