Answer:
Step-by-step explanation:
Given is a function
Since leading term is positive,
the parabola is open up.
Let us write this in vertex form after completing the square
Hence we get vertex= (-5/2,-1/4)
Since this is a parabola open up we have the minimum point is only one at x=-5/2
So we have the function decreasing for x<-2.5 and increasing for x>-2.5
Decreases in
Increases in
