Question #70a15

Answer 1

(a)`Lim_(x->-5) x^2/(2x-3)` = `((-5)^2)/(-10-3) = -25/17`

(b)`Lim_(x->2) (x^3-8)/(x-2)` =`Lim_(x->2) x^2 +2x+4`= 12

(c)`Lim_(x->-2) (x^3+8)/(x+2)`= `Lim_(x->-2) x^2 -2x+4`=12

(d)`Lim_(x->2) (x^2-4)/(x^2 -3x +2)`= `Lim_(x->2) (x+2)/(x-1)`=4

(e)`Lim_(x->0) (1/x-1/x^2)`= `Lim_(x->0) (x-1)/x^2`= `-oo`
