I don't understand this homework problem:
If 4x - 9 ≤ f(x) ≤ x^2 - 4x +7 for x ≥ 0, find lim x--> 4 f(x)
The f(x) in the middle is throwing me off. What's supposed to be there so I can solve it?

-
Knowing what f equals is irrelevant for this question.
Since lim(x→4) (4x - 9) = 7 = lim(x→4) (x^2 - 4x + 7), we conclude by the Squeeze Law
that lim(x→4) f(x) = 7.
I hope this helps!
