Identify intervals on which the function is (a) increasing, (b) decreasing, and (c) constant. In each case, assume that the domain of the function is (-∞, ∞) and that any characteristics of the graph continue as indicated. Q(t) = 2(2 - t) + 4t

Answer :

Explanation:

Given the inequality:

Q(t) = 2(2 - t) + 4t

The derivative of this is:

Q'(t) = 2(-1) + 4

= -2 + 4 = 2 > 0

The function is always increasing
