please explain how to solve this, Thank you

Without graphing, answer the following questions for each of the functions below: i. What are the end behaviours of this type of function (what quadrant does it begin and end in?) ii. What is the maximum and minimum number of x-intercepts for this type of function? iii. What is the maximum and minimum number of turns for this type of function? iv. State if there are any restrictions on the domain and range on this type of function. It may be easiest to format your answer by setting up a chart with the headings "End Behaviours, Maximum number of x-intercepts, Minimum number of x-intercepts, Maximum number of turns, Minimum number of turns, and Restrictions", then filling in your answers for the functions listed. a) f(x) = 24 + 8x3 + k b) f(x) = 26 + kx - 9x2 - 27 " f(x) = - 2x7 - 441x3 + k
