The following function represents the production cost f(x), in dollars, for x number of units produced by company 1: f(x) = 0.05x2 − 7x + 300

The following table represents the production cost g(x), in dollars, for x number of units produced by company 2:

x g(x)
0.6 899.58
0.8 899.52
1 899.50
1.2 899.52
1.4 899.58

Based on the given information, determine which company has a lower minimum and find the minimum value.
A. f(x) at (1, 899.50)
B. g(x) at (70, 55)
C. f(x) at (70, 55)
D. g(x) at (1, 899.50)

step-by-step explanation:

i took the test: )

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'.
