Use the Intermediate Value Theorem to show that the function has at least one zero in the interval [a, b]. (You do not have to approximate the zero.)

f(x) = x5 − 8x + 3,

    [−2, −1]

f(-2)=

f(-1)=

Because f(−2) is ??? positive negative and f(−1) is  ??? positive negative , the function has a zero in the interval [−2, −1].

Suppose f(x)=x6+3x+1f(x)=x6+3x+1. In this problem, we will show that ff has exactly one root (or zero) in the interval [−4,−1][−4,−1]. (a) First, we show that f has a root in the interval (−4,−1)(−4,−1). Since f is a SELECT ONE!!!! (continuous) (differentiable) (polynomial)   function on the interval [−4,−1] and f(−4)= ____?!!!!!!! the graph of y=f(x)y must cross the xx-axis at some point in the interval (−4,−1) by the SELECT ONE!!!!!!
