Given:
28/36 ratio
annual income: 86,250
28+36 = 64
28/64 * 86,250 = 0.4375 * 86,250 = 37,734.375
36/64 * 86,250 = 0.5625 * 86,250 = 48,515.625
28/36 ⇒ 37,734.375/48,515.625
we are given
![f(x)=(0.75)^x+2](https://tex.z-dn.net/?f=%20f%28x%29%3D%280.75%29%5Ex%2B2%20)
For finding asymptote , we can find limit
![\lim_{x \to \infty} f(x)= \lim_{x \to \infty}((0.75)^x+2)](https://tex.z-dn.net/?f=%20%20%5Clim_%7Bx%20%5Cto%20%5Cinfty%7D%20f%28x%29%3D%20%5Clim_%7Bx%20%5Cto%20%5Cinfty%7D%28%280.75%29%5Ex%2B2%29%20)
![\lim_{x \to \infty} f(x)= \lim_{x \to \infty} (0.75)^x+\lim_{x \to \infty} 2)](https://tex.z-dn.net/?f=%20%20%5Clim_%7Bx%20%5Cto%20%5Cinfty%7D%20f%28x%29%3D%20%5Clim_%7Bx%20%5Cto%20%5Cinfty%7D%20%280.75%29%5Ex%2B%5Clim_%7Bx%20%5Cto%20%5Cinfty%7D%202%29%20)
now, we can solve it
![\lim_{x \to \infty} f(x)= 0+2](https://tex.z-dn.net/?f=%20%20%5Clim_%7Bx%20%5Cto%20%5Cinfty%7D%20f%28x%29%3D%200%2B2%20)
![\lim_{x \to \infty} f(x)= 2](https://tex.z-dn.net/?f=%20%20%5Clim_%7Bx%20%5Cto%20%5Cinfty%7D%20f%28x%29%3D%202%20)
so, horizontal asymptote is
.............Answer
y = 7 + 3x
y = 3x + 7
y = mx + b, therefore the y-intercept is 7.
3y = 6x + 12
y = 2x + 4
y = mx + b, therefore the y-intercept is 4.
In this case 'g' would be 5 - 7f
I'm pretty sure its 127.8
