Question

Ajutati-ma si pe mine, va rog.
Cat este: lim 3 cand x tinde catre 3 ?
Lim (3x la puterea 2 -x+2) cand x tinde catre 1
Lim (5 la puterea3+1) cand 5 tinde catre + infinit

Answer 1

$\lim_{x \to \ 1} 3x^2-x+2= 3-1+2=4$

Answer 2

$\lim_{x \to 3} 3=3 \\ \lim_{x \to 1} (3x^2-x+2)=3 \cdot 1^2-1+2=3 \cdot 1-1+2=3-1+2=4$
