Complete each statement. 11. The local extrema are found by solving the equal to zero 12. The points of inflection are found by solving the equal to zero. 13. If a function is an decreasing function, in terms of its derivatives, it means that all values of the first derivative are 14. To determine the horizontal asymptotes, take the limit of the function as x approaches 15. The point where a function changes its is called the point of inflection. 16. To determine the behaviour of a function near its asymptotes, limits are used. 17. Vertical asymptotes are only found with functions. 18. To determine the absolute maximum or minimum, consider the of the interval as well as the local extrema
