In your question, you're told that the function f of s represents the total cost of producing a solid -state drive that can store s gigabytes.
00:14
It says you're to use function notation to answer your question.
00:18
So function notation needs to be used.
00:25
And what i realized right away is we weren't actually given the expression for the function.
00:30
We were just given the name of the function.
00:32
And when we use function notation, we will put values in place of the s that represent the answer to the question.
00:42
We won't be able to actually get the answer, numerical value, just have a symbol that represents the answer.
00:53
So in part a, it is how much will it cost the company to create an ssd of 256 gigabytes.
01:03
So all you need to do for your answer would be to write f of 256.
01:09
This is function notation for the cost of 256 gigabytes.
01:16
In part b, this one they want to say what is the increase in cost in dollars to produce a 512 gigabyte storage instead of one with 256.
01:28
So the cost difference would be to find the value or the cost of the 512 gigabyte...
