Answer Happy

Using the intermediate value theorem, determine, if possible, whether the function t has at least one real zero between a and b. f(x)=x3+2x2−7x−4;a=−9,b=−3 Select the correct chcloe below and, it necessary, ill in the answer boxes to corrplete your cheice. A. By the intermediate value theorem, the furiction has at least one feal zero between a and b because f(a)= and (b)​= (Simpify your arsavera.) B. By the intermediate vakie theocem, the function does not have at least one reas zero between a and b because f(a) = C. It is impossible to wse the intermedale value theorem in this case.
