    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?

    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.

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