Answer:
28%
Step-by-step explanation:
In the function the .72 means that each unit of time 72% of the value is retained. This means that 28% percent of the value is lost or decays because 1-0.72=0.28 or 28 percent.
So,first step is to write ![(fog)(-4)) =f[g(-4)] \\](https://tex.z-dn.net/?f=%20%28fog%29%28-4%29%29%20%3Df%5Bg%28-4%29%5D%20%5C%5C%20)
Now we start from inner paranthesis
,we need to first find value of
I get the answer being the same y= -1/2x +
Because b in intercept form is "0"
I used
m=y2-y1/x2-x1
M=-3-2/6-4
M=-5/10
M=-1/2
(-4,2)
Y=mx+b
2=-1/2 (-4)+b
B=2-(-1/2)(-4)
B=0
I did the same for second point
And got "0" for b
So my answer is get
Y=-1/2x
Unless someone else gets something else different.
I hope somewhat helps
