Question: Using the intermediate value theorem, determine, if possible, whether the function f has a zero between a and b. a. f(x) = 4x2 - 5x

Using the intermediate value theorem, determine, if possible, whether the function f has a zero between a and b.
a. f(x) = 4x2 - 5x - 3; a = 1, b = 2
b. f(x) = x3 - 4x2 + ½x + 2; a = - 1, b = 1
