Consider the fuction f(x)=x^4-3x^3-7x^2+15x+18
a. find the possible rational roots of f(x)=0
b. use synthetic division to divide f(x) by x-3. show all your work. use your answer to explain whether or not x-3 is a factor of f(x).
c. factor f(x) completely. show all your work!
d. sketch the graph of f(x) by plotting the x-intercepts, finding and plotting additional points on the graph, and using what you know about the graph's end behavior.
