Evaluate the function for the given values of a and b. Then use the intermediate value theorem to determine which of the statements below is true.a = 1 and b = 2f(x) = 2x3 + 4x2 - 9x - 9
A. f(1) and f(2) have the same sign, therefore the intermediate value theorem cannot be used to determine whether the function f has a real zero between 1 and 2.
B. f(1) and f(2) have the same sign, therefore the function f has a real zero between 1 and 2.
C. f(1) and f(2) have opposite signs, therefore the function f does not have a real zero between 1 and 2.
D. f(1) and f(2) have opposite signs, therefore the function f has a real zero between 1 and 2.

Solve the problem.From a 32-inch by 32-inch piece of metal, squares are cut out of the four corners so that the sides can then be folded up to make a box. Let x represent the length of the sides of the squares, in inches, that are cut out. Express the volume of the box as a function of x.
A. V(x) = 2x3 - 96x2 + 32x B. V(x) = 2x3 - 96x2 C. V(x) = 4x3 - 128x2 D. V(x) = 4x3 - 128x2 + 1024x
