Using the intermediate value theorem, determine, if possible, whether the function f has at least one real zero between a and b. f(x) = x3 + 2x2 - 9x-5; a = -8, b = - 3

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
