Answer:
A. -f(1/2 x)
Step-by-step explanation:
Reflextion about the x-axis is
f(x) -> -f(x)
and horizontal dilation is
f(x) -> f(-x/b) where b is the factor of dilation.
so the proper answwer is
A. -f(1/2 x)
Answer:$18200
Step-by-step explanation:
Find the depreciating price after one year
7% of 28000
7/100* 28000=$1960 is the depreciating cost
Multiple the depreciating cost by 5 year
1960*5=9800
Actual cost - depreciating cost after 5 year
28000-9800= $18200
Let's say that the unknown value here is c. Although we are given two points on the line, it is only necessary to use one as there is only one unknown value, so let's say we choose the point (6, -12) and substitute this into the equation:
-12 = 1(6) - c
-12 - 6 = -c
-18 = -c
c = 18
Thus the equation for the line is y = 1x - 18
