The function f(x)= kx^3 - 8x^2 -x + 3k + 1 has a zero when x=2. determine the value of k. graph f(x) and determine all the zeros. then rewrite in factored form. i found that k=3 so far, but i'm not sure how to graph it without making a table of values, or how to find the zeros. any ideas?

Will mark brainliest for correct answer! i have been on this problem for an hour and can't find the answer. i'm begging here! incase you cant read the instructions in the picture because of too much or too little lighting: note: enter your answer and show all the steps that you use to solve this problem in the space provided.write a list of steps that are needed to find the measure of b. provide all steps as clear as possible, !
