22. The rate of change of a function y with respect to x equals 2-y , and y = 8 when x = 0. Find y when x = In 2. A) 2 B) -5 C) 5 D) -2 23. Evaluate the integral of (3x2 + 9y )dxdy if the interior limit has an upper limit of y and a lower limit of 0, and whose outer limit has an upper limit of 2 and a lower limit of 0
