Question

( lim _{x rightarrow infty} frac{(x+1)(3 x+4)}{x^{2}(x-8)} )
( =lim _{x rightarrow infty} frac{x^{2}left(1+frac{1}{x}right)left(3+frac{4}{x}right)}{x^{3}left(1-frac{8}{x}right)} )
( =frac{1+left(1+frac{1}{x}right)left(3+frac{4}{x}right)}{xleft(1-frac{8}{x}right)} )
( x rightarrow infty )
( =0 ) and

# The value of lim (4+1)(3x+4) X 700 is equal to (a) 2 (C) 1 (b) 3 (d) 0 40.
