Are you sure that's how the problem is given, because practically what you're saying is:\[f(x) = 5x-\]if\[x<-2\]and \[f(x)=x-9\]if\[x <> -2\]Did you maybe mean on the second choice x greater than or equal to -2?

yes sometimes i get confused

lol.. no worries. Well if that's the case then it means that if x=-2, you need to evaluate the function somewhere where it is defined like that. Since the function is saying f(x)=x-9 IF x is greater or equal to -2, then you need to evaluate the function at that expression. Try that, and show me the result you got.

-11 for both

Yes, but you don't need to evaluate both. You just need to evaluate f(x)=x-9... But you're correct anyhow.
