Find the range of the function f(x) = 3x - 2, given the domain {-4, 0, 4}

{-14, -2, 10}

Step-by-step explanation:

To find the range, you can use all the domain values and find the output.

f(-4) = 3(-4) - 2

f(-4) = -12 - 2

f(-4) = -14

f(0) = 3(0) - 2

f(0) = 0 - 2

f(0) = -2

f(4) = 3(4) - 2

f(4) = 12 - 2

f(4) = 10

Best of Luck!

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'.
