Can you pls answer the question clearly ?

Use the first derivative and the second derivative test to determine where each function is increasing, decreasing, concave up, and concave down. y= - 2x2 - 3x + 1, XER Select the correct choice below and, if necessary, fill in the answer box to complete your choice. y = 19xe-X, x > 0 A. The function is increasing on the interval(s) (Type your answer in interval notation. Use a comma to separate answers as needed. Type an integer or a simplified fraction.) Select the correct choice below and, if necessary, fill in the answer box within your choice. O B. The function is not increasing on any interval O A. The function is increasing on (Type your answer in interval notation. Use integers or fractions for any numbers in the expression. Simplify your answer.) b y=x3 - 2x2 + x + 1, XER O B. The function is not increasing on any interval. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. 3x + 5 -, x#0 O A.
