    y -intercept where line cross y-axiss and x-intercept where line cross x-axis did you graph it on a calculator ?

    if the highest degree is a odd number and the leading coefficient is negative then right end will fall and left end will rise **and if the leading coefficient is positive then right side will rise and left will fall

    btw you DON'T have to for y-intercept (when line touch the y -axis x=0) so plug in 0 for x solve for y x-intercept when y =0 so plug in 0 for y solve for x

    nah i can easily figure out that graph is wrong bec highest degree is odd which is 3 your graph should be like this |dw:1437394937194:dw|

    highest degree is 3 so = 3 x-intercept

    desmos.com graph the equation zoom out a little bit you will see the point where line cross y-axis that is your y-intercept

    or \[\huge\rm y =x^3 +15x^2 +68x-96\] or replace x by 0 solve for y

    nope when line cross y-axis x equal to 0 so x is 0

    increasing because the leading coefficient is positive
