-Why don't you divide it up-

I'm just playing around and asking-

I did it.

0 Let u=a minus the square of X plus the power of 3x+2.

Is the formula u=-(x-3/2)? + 17/4

So the function u

In the interval (-∞, 3/2), it is increasing function.

Discussion on the Decreasing Function in the Interval [3/2, -∞]. 1

When 0 < a < 1, it is a decreasing function.

Show the same increase and different decrease.

So the original function is a decreasing function in the interval (-∞, 3/2) and a increasing function in the interval [3/2,-∞).

2 when a > 1, it is increasing function. Similarly, the original function is increasing function in the interval (-∞, 3/2), and it is a decreasing function in the interval [3/2,-∞).
