Answer:
[tex]f(x)=128-14x[/tex]
Step-by-step explanation:
So, we started out with 128 ounces of milk.
Each day, Joann drinks 14 ounces of milk.
Therefore, the amount of milk left over after x days is 14 times x subtracted from 128.
Therefore, our function is:
[tex]f(x)=128-14x[/tex]
And we're done!
