Find f(5)

Answer 1

I can’t reliably read the piecewise definition from what you typed — the formatting got garbled. I need to know which formula applies at x = 5 (or what the rule is for x ≥ 5 or x = 5).

Could you retype the piecewise function clearly, for example like this:

f(x) = { (5x−9)/2, x < 1
-x−3, x = 1
1, 1 < x < 5
???, x ≥ 5 }

(or whatever the actual pieces are).

If you prefer, just tell me the rule that applies when x = 5. Once I have that I’ll compute f(5).
