Determine which consecutive integers do not have a real zero of f(x)=x^3+9x^2+8x-5 between them.

-8,-7
4,5
0,1
-2,-1

Aperecent is the answer

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post

Ithink it is correct but just ask someone else but i am sure it it
