Given the two functions $f$ and $g$, find $f+g$ and identify the domain.
$f\(\left\)(x\(\right\))=11x^2-3x-7$, $g\(\left\)(x\(\right\))=3x-4$

• A. $\(\left\)(f+g\(\right\))\(\left\)(x\(\right\))=11x^2+11$, Domain: $\(\left\)(-\(\infty\),-1\(\right\))\(\cup\[\left\)(-1,\(\infty\]\right\))$
• B. $\(\left\)(f+g\(\right\))\(\left\)(x\(\right\))=11x^2-6x+11$, Domain: $\(\left\)(-\(\infty\),1\(\right\))\(\cup\[\left\)(1,\(\infty\]\right\))$
• C. $\(\left\)(f+g\(\right\))\(\left\)(x\(\right\))=11x^2-11$, Domain: $\(\left\)(-\(\infty\),\(\infty\]\right\))$
• D. $\(\left\)(f+g\(\right\))\(\left\)(x\(\right\))=11x^2+6x-11$, Domain: $\(\left\)(-\(\infty\),\(\infty\]\right\))$
