? 7. The critical values of a function f are precisely the x-values in the domain of f such that f'(x ) = 0. ? 8. A function may achieve a global maximum at an x-value that is not a critical value. ? + 9. If we are given the graph of f'(x ), then there is only one possible function f(x) that we could sketch with the correct derivative. 10. If f and q are increasing on an interval I, then fo is also increasing on
