What is the answer for question 5. a) ? http://postimg.org/image/f5d950icj/
For a function defined by y = f(x), the set of values in which x lies is called the domain and the set of values in which y lies is called the range.
From the graph of the function that is given it is seen that the domain consists of the set [2, 5] and the range consists of the set [-2, 2]
The domain of the given function is [2, 5] and the range is [-2, 2]
