Description Lines can be used to approximate a wide variety of functions; often a function can be described using many lines. If a stock price goes from $10 to $12 from January 1st to January 31, and from $12 to $9 from February 1st to February 28th, is the price change from $10 to $9 a straight line? How can I use two “pieces” of lines to describe the price movements from the beginning of January to the end of February?
Description Alice was having a conversation with her friend Trina, who had a discovery to share: Pick any two integers. Look at the sum of their squares, the difference of their squares, and twice the product of the two integers you chose. Those three numbers are the sides of a right triangle. Write an equation that models this conjecture using the variables x and y.
Description 1. Give an example of a function, f(x), with a domain of (0,5] and a range of [0,?) 2. If f(t) = 2t – t2, what is (f(t + h) – f(t)) / h? 3. If F = { (1,2), (3, 5), (4,7)} and G = { (1,4), (3,0), and (5, 2)}, what is F + G? What is G/F (using arithmetic function)?
Description Decide whether the following statement makes sense (or is clearly true) or does not make sense (or is clearly false). Explain your reasoning. My freeway speed is the rate of change in my distance with respect to time. Choose the correct answer below. A.The statement does not make sense because the slope of a linear function is the change in the independent variable divided by the change in the dependent variable. B.The statement makes sense because the slope of a linear function is the change in the independent variable divided by the change in the dependent variable. C.The statement does not make sense because the slope of a linear function is the change in the dependent variable divided by the change in the independent variable. D.The statement makes sense because the slope of a linear function is the change in the dependent variable divided by the change in the independent variable.
