16 points. find the x and y intercepts of number 8 show work. i think my points are wrong.

Again, I'd try graphing this thing and get your point this way. Go to Wolframalpha dot com Put
y = 2x^4 + 3x^3 - 16x - 24 into the input line.
According to wolframalpha there are 2 real roots and 2 imaginary ones.

there are places on the internet that will solve quartics for you and likely those solutions will show all 4 roots. You were right to be a little suspicious, but the question is a bit unreasonable.

Note to Moderator. Wolframalpha dot com is just a tool. the work is my own.

Distance=slopeslope is -2/4which equals-1/2the distance between these two points is -1/2
