The answer is (6,8],because it has no minus sign in front of it

Answer from: Loowkeychrissy7227

(-4,0) and (6,8)

Step-by-step explanation:

We have been given the graph and we have to determine where the function is positive.

In order to find the same, we see at which intervals the graph of the function is above x- axis.

The function is positive if the graph is above the x axis.

Looking into the given graph, we can see that the graph is above x axis at (-4,0) U (6,8).

Hence, the graph is positive at

(-4,0)

and (6,8)

Answer from: natalie407888

(-2,4) & (4,8] are positive

Answer from: yukichaniscool8

B. (-8, -6) D. (-2, 4)

Step-by-step explanation:

The y-value is positive when x is between -8 and -6 and when x is between -2 and 4.

So, the interval when y is positive is (-8, 6) ∪ (-2, 4).

Answer from: brockandersin

Alright, lets get started.

When teh function is above the x axis, it is said to be positive.

When the function is below the x axis, it is said to be negative.

Now, looking at the graph provided with question, from -8 to -6, the function is above the x axis.

After -6, function goes below the x axis till -2.

In between -2 to 4, function again goes above x axis.

Means two times function goes above the x axis.

Between -8 to -6

Between -2 to 4

Hence there are two intervals where function is positive.

[-8,-6)and(-2,4)

Hope it will help :)
