In Exercises 39-50, sketch the graph of the function with the given rule. Find the domain and range of the function. 49. f ( x ) = { − x + 1 if x < 2 x 2 − 1 if x > 1
In Exercises 39-50, sketch the graph of the function with the given rule. Find the domain and range of the function. 49. f ( x ) = { − x + 1 if x < 2 x 2 − 1 if x > 1
Solution Summary: The author explains that the given function is a piecewise defined function. It is defined as f(x)=-x+1.
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?
In Exercises 7 and 8, which of the graphs are graphs of functions of x, and which are not? Give reasons for your answers
