Over which interval is the graph of f(x) = x2 + 5x + 6 increasing?

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

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
