use formal definition for formal proof (limits)

[asifrahman1988]

Use an appropriate formal definition to give a formal proof of each of the following.


(a) lim (x³− 5x+6) = 2
x→1



(b) lim 9-4x² _{= 6}
x→ −1.5 3+2x



(c) lim 1 _{= ∞}
x→ −3 (x+3)⁴


(d) lim lnx = - ∞

(b) lim 9-4x² _{= 6}
x→ −1.5 3+2x



(c) lim 1 _{= ∞}
x→ −3 (x+3)⁴


(d) lim lnx = - ∞
x→0⁺


I'm sorry, i can't get the formatting right. I hope this is enough
