Remaining Time: 1 hour, 23 minutes, 00 seconds. Question Completion Status: QUESTION 3 du dx Is the function y = \\ 5- 3x increasing or decreasing at the point ( 1 , ( 2 ) and explain why? (Hint: dx 2/ u a. decreasing at all values of x especially at x = 1 since its first derivative dy -3 changes signs from positive to negative near x = 1 dx 21 5- 3x O b. decreasing at all values of x especially at x = 1 since its first derivative dy -3 dx changes signs from negative to positive near x = 1 21/ 5 - 3x " decreasing at all values of x in the Domain of the original function y = \\ 5- 3x especially at x = 1 since its first derivative: dy - 3 dx is stricly negative for all values of x 25 - 3x in the Domain of the original function y = \\ 5- 3x O d.
