12 +8x + 15 x +8x+15 Explain why lim = lim (x+5), and then evaluate lim X43 8 -3 X- -3 X+3 Choose the correct answer below. OA. x2 +8x + 15 The limits lim x +3 and lim (x + 5) equal the same number when evaluated using direct substitution. X- -3 * - - 3 O B. Since each limit approaches - 3, it follows that the limits are equal O C. x2+ 8x +15 Since x +3 -= x +5 whenever x # - 3, it follows that the two expressions evaluate to the same number as x approaches - 3. OD. x2+8x+15 The numerator of the expression x+3 simplifies to x * 5 for all x, so the limits are equal
