Answer:
a = - 1.1
Step-by-step explanation:
Condition for a single variable function f(x) to be decreasing is f'(x) < 0.
So, in our case, 
.
Then, differentiating with respect to x on both sides we get,
⇒ 
⇒ 
{Dividing both sides with - 1 and hence the inequality sign changes}
⇒ 
⇒ 8 > - 6x³ {Multiplying both sides with x³}
⇒ 6x³ > - 8 {Interchanging the sides}
⇒ 
⇒ x > - 1.1
Therefore, a = - 1.1. (Answer)
