Example: Evaluate lim ox +4x2+5 X-+00 8x3+7x-3 Solution: The function assumes the indeterminate form - when x is replaced by co. Dividing the numerator and denominator by x3, we get 6x3+ 4x2 + 5 6+ + = lim x-+00 8x3 + 7x -3 = lim X-+00 8 + 6+0+0 ALW 8+0+0 Evaluate each of the following. 1. lim 3x +x+2 x-+00 x3+8x+1 2. lim 4x+5 X+00 x3+1 3. lim * +x+2 x400 x2-1 4. lim (x+2)3-(x-2)3 X-+00 x2 5. lim X+00 (2x-1)3
