please explain 2. The graph of y = cosh a is(a) concave up on its entire domain because y" = cosh r > 0 for all r E (-0, 00).(b) concave down on its entire domain because y" = - cosh a < 0 for all æ E (-0, 00).(c) increasing on its entire domain because y' = sinh r > 0 for all r € (-x, 0).(d) decreasing on its entire domain because y' = sinh r < 0 for all r € (-0, 00)(e) None of the above.
