Question

f(x)= 3x^3-8x-26/3x^2+11x+10

the function has:

 A y intercept at the point    

2) x intercepts at the point(s)    

3) Vertical asymptotes at x =    

4) Horizontal asymptote at  y =

Answer 1

graph it, use desmos graphing calculator or any online or hand held calculator

see where the graph intersects the x axis, that's the x intercept(s).

use decartes rule of signs,

1 possible positive zero

2 possible negative zeros

2 imaginary or negative real zeros and 1 positive real zero

the 1 positive zero is between 1 and 2

any negative real zeros are between -1 and -2

between x = 1 and 2 there's a sign change

between x =-1 and -2 is a sign change

that's where any zero has to be
