I am having trouble with this question. A function is shown below: f(x) = x3 + 4x2 - x - 4 Part A: What are the factors of f(x)? Show your work. Part B: What are the zeros of f(x)? Show your work. Part C: What are the steps you would follow to graph f(x)? Describe the end behavior of the graph of f(x).

    With Part A and B I think I got the answer but I was having trouble with C, I wanted to make sure A and B were right. I got for A (x+1) (x-1) (x+4) and for B -1, 1, -4

    graph when x = 0 what is y? when y = 0 what are the x values? plot the points consider any exclusions you can use test points to consider end behaviour

    easy ust break them up x2 (x+4) -1(x+4) and youve got your equation of (x2 - 1) (x+4) ive done this many times before and took college classes where they taught it to us this way:) good luck:)
