Just need somebody to double check a few problems for me.
lim 9-x^2/x-3
x->3
lim -(x-3)(x-3)/x-3 =
x->3
-(x+3) = -(3+3) = -6
Next problem
lim x^2 +x-6/x-2
x->2
Lim (x+3)(x-2)/x-2 =
x->2
lim x+3=
x->2
2+3=5
You got them right!Originally Posted by becky
A tip. Your first problem is:
$\displaystyle \lim_{x \to 2}\frac{9-x^2}{x-3}$
If you click on the expression above it will tell you how to code it in LaTeX. Otherwise you might want to consider using parenthesis so that your expression is unambiguous.
