(i) Direct substitution

Evaluate the following by the Method of Direct Substitution : lim_(x rarr 3)(x+3) .

Evaluate the following by the Method of Direct Substitution : lim_(x rarr 4)(4x+3)/(x-2) .

Evaluate the following by the Method of Direct Substitution : lim_(x rarr -1)(x^10+x^5+1)/(x-1) .

Evaluate the following by the Method of Direct Substitution : lim_(x rarr 1)(ax^2+bx+c)/(cx^2 + bx+a),a+b+c ne 0 .

Statement-II : Most o-,P- directing substitution are deactivating. Because Because Statement-II : o-,p- directors have at least one ione pair of non-bonding electrons.
