At least one of the answers above is NOT correct. (1 point) Suppose /(x) = x + 3x + 1. In this problem, we will show that has exactly one root (or zero) in the interval (-3,-1). (a) First, we show that f has a root in the interval (-3,-1). Since is a continuous function on the interval (-3, -1) and f(-3) = and f(-1) = -1 the graph of y = f(x) must cross the X-axis at some point...
