Take Note: Define function notation.
Take Note: Provide an example of a function that is written in function notation.
Take Note: Rewrite the function rule using function notation.
Problem 3 Got It? Use the function in Problem 3, w(x) = 250x. How many words can you read in 6 min? Enter only a number.
Problem 4 Got It?
Take Note: Explain what is meant by identify a reasonable domain and range.
Hint: This applies when representing a real-world scenario with a function.
