Answer:
a)
![f(x) = (4)/(x-8) - 3.5](https://img.qammunity.org/2021/formulas/mathematics/college/27h449wfs56043io97bebniwcee37fa80o.png)
Explanation:
The y intercept of g(x) is the value of g when x = 0.
In this problem
![g(x) = √(x+4) - 6](https://img.qammunity.org/2021/formulas/mathematics/college/mz2e5i5ztr3st16o4xc88cjdwbrurmrrtq.png)
The y-intercept is
![g(0) = √(0+4) = √(4) - 6 = 2 - 6 = -4](https://img.qammunity.org/2021/formulas/mathematics/college/fgg8k7nyk2gkc4e13fzda9hukp56wqt82d.png)
a)
![f(x) = (4)/(x-8) - 3.5](https://img.qammunity.org/2021/formulas/mathematics/college/27h449wfs56043io97bebniwcee37fa80o.png)
The y-intercept is:
![f(0) = (4)/(0-8) - 3.5 = -0.5 - 3.5 = -4](https://img.qammunity.org/2021/formulas/mathematics/college/ztvwvihsyi0yapv2drjzufgb1a9511vgs3.png)
This is the correct answer
b)
![f(x) = -(4)/(x) - 1](https://img.qammunity.org/2021/formulas/mathematics/college/wpoiagygxeg1ulw7ffgrcik85go72vb8gb.png)
The y-intercept is
![f(0) = -(4)/(0) - 1](https://img.qammunity.org/2021/formulas/mathematics/college/zhbai1ikqdjicy0yje4xqood015e89z4yu.png)
This is an asymptote
c)
![f(x) = 2|x+2|](https://img.qammunity.org/2021/formulas/mathematics/college/rgvkzds88ok2gaa1njrsjv01thzo0o9618.png)
The y-intercept is
![f(0) = 2|0+2| = 4](https://img.qammunity.org/2021/formulas/mathematics/college/rd5hgkjkaymjil5fbi4vdbd43fc4070w0n.png)
d)
![f(x) = |x - 4|](https://img.qammunity.org/2021/formulas/mathematics/college/ffq8r83kp4m9iodsj1dthuqvhn2xuxsl9j.png)
The y-intercept is
[tex]f(0) = |0-4| = |-4| = 4.
