that's the interval from negative three to zero. when the function is graphed it is increasing on this interval, in addition to (3, infinity), (-3, 0) is the interval where the function is increasing with the lowest value of A.

what is the value?

thats what i need along with the work shown.

an interval is from a certain x, to a greater point of x and the region of the graph selected. when you look at the graph of the t function (original) it is obvious that the function is increasing from x=3 to x=0 where A is the smallest on an increasing interval
