Answer:
The function f(x) is represented by:
![f(x)=1500(0.97)^x](https://tex.z-dn.net/?f=f%28x%29%3D1500%280.97%29%5Ex)
Hence, a=1500 and b=0.97
Step-by-step explanation:
The patient currently has a bone density of 1,500 kg/mg^3.
A doctor estimates that a particular patient is losing bone density at a rate of 3% annually.
This means that the bone density that is remaining is:
100-3=97%
which is also represented as: 97%=97/100=0.97
Hence, the function f(x) that represents the bone density after x years is represented by:
![f(x)=a(0.97)^x](https://tex.z-dn.net/?f=f%28x%29%3Da%280.97%29%5Ex)
where a is the initial bone density which is given to be: 1500 kg/mg^3.
Hence, the function is:
![f(x)=1500(0.97)^x](https://tex.z-dn.net/?f=f%28x%29%3D1500%280.97%29%5Ex)
Since the slope-intercept form of a line is given by the expression:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Where, m is the slope and b is the y-intercept.
Then, for the function:
![y=-2x+3](https://tex.z-dn.net/?f=y%3D-2x%2B3)
The slope is -2 and the y-intercept is (0, 3)

= (7x4) x 10^-7
= 28 x 10^-7
= 2.8 x 10^-6</span>
