Answer 1

$\displaystyle \lim_{x \to \ -1}(x^2+1)= \lim_{x \to \ -1}((-1)^2+1)=2\\\\ \lim_{x \to \ 2}(x^2-1)= \lim_{x \to \ 2}(2^2-1)=3\\\\ \lim_{x \to \ -1}(2x^2-1)= \lim_{x \to \ -1}(2*(-1)^2-1)=1\\\\ \lim_{x \to \ -2}(2x^2-3)= \lim_{x \to \ -2}(2*(-2)^2-3)=5\\\\ \lim_{x \to \ -2}(2x^2+3)= \lim_{x \to \ -2}(2*(-2)^2+3)=11\\\\ \lim_{x \to \ -1}(2x^2-x)= \lim_{x \to \ -1}(2*(-1)^2-(-1))=3$
