just put the one by one , each element of set domain into the given function and get the range for each element.

haseeb96 · Answer

like if the function is this f(x) = 2x +1 and domain is 2
now find the range 
i will just put the domain at the place of x in the given function 
f(2)= 2(2)+1
     = 4 +1 
     = 5 
so 5 is your range

i dont get it i get decmals and it is not the correct answer @Haseeb96

haseeb96 · Answer

okay let me solve it 
first put -4 in the function at the place of x
f(-4)= 12 -3(-4)
       =12  +12
        =24
24 is the range  of -4 
now solve it yourself
