5 . Determine a value of a so that the following limit will exist: lim 3x tax+ a-13 * - - 2 2x2 + 3x -2 Give also the limit for your value of a. Hint: the bottom (denominator) is 0 when x = -2. The limit can exist only if the top (numerator) is also 0 when x = -2, so that the limit has the indeterminate form
