Use the graph to interpret and match the approximate intervals with their descriptions. Drag the tiles to the correct boxes. Not all tiles will be used.

We first look at the graphic, and then, we analyze it, completing the tiles.

Graphic:

From the graphic, the function is increasing in two intervals: and

On the middle, that is, , it can be said that the function is decreasing.

Interval over which the difference is increasing:

The function is increasing over two interval, and , so the corresponding tile is:

(4.9, 10).

Interval over which the difference is decreasing:

Between -9 and 4.9 the function is decreasing, so the corresponding tile is:

(0, 4.9).

Interval over which the difference is positive:

An interval where the function is above the x-axis, so between -9 and -3, and then above 10, so the corresponding tile is:

(-9,-3)

Interval over which the difference is negative:

An interval where the function is below the x-axis, so before -10, and then between -3 and 10. Thus the corresponding tile is:

(-3,10).

For another question on graphic interpretation, you can check

d. is the correct answer

step-by-step explanation:

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
