Suppose that f has a domain of [7, 17] and a range of [8, 14].
(a) What are the domain and range of the function y = f(x) + 4?
(Use symbolic notation and fractions where needed. Give your answers as intervals in the form (*, *). Use the symbol \infty for
infinity and the appropriate type of parenthesis "(", ")", "[", or "]" depending on whether the interval is open or closed.)
