2) Give an example of a function whose domain is [-2, 2].
Here are two graphs representing the function f given by f(x) = 10 . 2* and the function g defined by g(x) = a • b*. (2, 48) - (1, 12) (0,3) 1. Is b greater than or less than 2? Explain how you know, 2. Write an equation that defines g. Show your reasoning. 3. f and g represent the number, in thousands, of social media followers of two organizations as a function of years since 2010. What does the intersection of f and g mean in this context?
The musical note E can be modeled by the function, y = asin(1320πx), where a = 1 and x is the time in seconds. Playing note E on your computer, you notice that it is not loud enough to be heard across the room.
What change can you make to the function to make note E louder than the original?
