Question 1 [3+4+3] Given the function y = g(x) with g'(x) = 3x2-9 3x2 -9 2Vx3 - 9x 2Vx(x-3)(x+3). 1.1 If g and g' has the same domain, find the domain of g and represent using set notation. Show steps and use graphs to solve the inequality. Hint: The function y = x(x - b) (x + b) is a cubic function with the following shape. 1.2 Show how you use the definition to identify the x -value(s) of the critical point(s) of g
