QUESTION 9 Construct a Sign Chart for the following polynomial function and state the intervals where this function is positive and where this function is negative. f(x) = 2x2(2 -x)3(2x+ 3) Note: Suppose a function is positive from -2.5 to 1 and from 1 to positive infinity. You would enter the intervals as (-2.5,1)U(1,+inf). There should be no spaces in your answer. Use decimals to the nearest tenth for rational critical values and a capital U for the union symbol.
