What is the average rate of change for ƒ(x) = 2x − 12 over the interval 4 ≤ x ≤ 8?

Therefore, the average rate of change is 2.

Step-by-step explanation:

The average rate of change  of for  over the interval  will be the slope of the  secant line  connecting the 2 points.

To calculate the average rate of change  of f(x) on the interval [a, b] is:

The average rate of change between (4, -4) and (8, 4) will be:

Therefore, the average rate of change is 2.

Step-by-step explanation:

idk what the answer is but for the points

step-by-step explanation:

the first one and the second one that's the answer

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
