Answer: f(n) = 0.9 × f(n − 1) + 10, f(0) = 175, n > 0
Step-by-step explanation:
Given: A store had 175 cell phones in the month of January.
Every month, 10% of the cell phones were sold and 10 new cell phones were stocked in the store.
Let n be the number of months
Then when n=0
f(0)=175
After first month , n=1
The number of cell phone in store=
Thus 
Similarly we can do till n months, we get
f(n)=0.9×f(n−1)+10, f(0) = 175, n > 0

Answer:
A subordinate clause—also called a dependent clause—will begin with a subordinate conjunction or a relative pronoun and will contain both a subject and a verb. This combination of words will not form a complete sentence. It will instead make a reader want additional information to finish the thought.
A function has only one y-value for each x-value. If you find a set that has an x-value used more than once, it is not a function, because that x-value is now paired with more than one y-value.
The fourth answer is the only one that has the same x-value used more than once.
Side note: Don’t worry if a y-value is used more than once. That’s totally fine. It’s all about the x-values.
If it’s 67.8 repeating then just put a bar on top of the .8 .
