Use properties of limits to find the indicated limit. It may be necessary to rewrite an expression before limit properties can be applied.

lim x --> 0 (2x2 + 2x + 3)2

A. 9
B. 1
C. -9
D. does not exist

Solution:

we have been as asked to use properties of limits to find the indicated limit.

The given limit is

[tex] \lim_{x->0}(2x^2+2x+3)^2 [/tex]

The given limit can be evaluated as below

[tex] \lim_{x->0}(2x^2+2x+3)^2=(2*0^2+2*0+3)^2\\
\\
\lim_{x->0}(2x^2+2x+3)^2=(0+3)^2\\
\\
\lim_{x->0}(2x^2+2x+3)^2=3^2\\
\\
\lim_{x->0}(2x^2+2x+3)^2=9\\
[/tex]

Hence the correct option is A.
