It doesn't simplify anymore
Idk........................why am i on this web sites with you noobs
C, it is a many-to-one function since it is symmetric about the line x=0.75.
For instance f(0.5) = f(1) meaning the x-values 1 and 0.5 both map onto the same y-value.
Answer:
y = 1.20x
Step-by-step explanation
Let's call x the length of the beams in feet
Llamemps f (x) at the price of beams.
The function represented by this model is the line y = 1.20x
Where 1.20 is constant price per foot.
If the price per foot is $ 1.20, then, the price of each beam according to its size is:
6 * 1.20 = $ 7.2
8 * 1.20 = $ 9.6
10 * 1.20 = $ 12
12 * 1.20 = $ 14.4
Then we have the following points, which will constitute the domain and rank for the function:
(6, 7.2)
(8, 9.6)
(10, 12)
(12, 14.4)
