all real nos.. @Ozymandios  is correct

anonymous · Answer

no it is not all real numbers

anonymous · Answer

the rule is $$y = 3x + 4$$ and if the domain is $$\{2, 9, 11.5 \}$$ then the range is what you get when you plug these three numbers in to the formula

anonymous · Answer

$$3\times 2+4=10,3\times 9+4=31, 3\times 11.5+4=38.5$$ so your range is 
$$\{10,31,38.5\}$$

Ty ! Whats (-3,0,1,4)?

anonymous · Answer

all real numbers was a reflex action from not reading the entire question
you have to plug the numbers in and see what you get

anonymous · Answer

i am sure you can compute the four numbers that would be the range
plug in $-3,0,1,$ and $4$ in to the formula $y=3x+4$ and see what you get
i.e take each number, multiply it by 3, add 4 and see what you get

anonymous · Answer

I got { -5 , 4 ,7 , 16} is that right?
