Step-by-step explanation:
Domain is the range of x-values for the function to be defined.
Domain of f(x) = [2,9]
Domain of g(x) = [2,9]
Answer:
720
g(-2)=2(-2)^3+3(-2)^2-3(-2)+4=-16+12+6+4=6
g(-1)=2(-1)^3+3(-1)^2-3(-1)+4=-2+3+3+4=8
it does not change sign ,so there is no real zero between -2 and -1.
