6. (8 points) Given f(x) = 2x3 + 6x2 - 8 (a) State the domain of f(x) in interval notation. (b) Find the x-and y-intercepts of the graph of f. Write answers as ordered pairs. Round to two decimal places, if necessary. (c) Determine whether the graph crosses or touches the x-axis at each x-intercept (label answer clearly). (d) Determine the maximum number of turning points on the graph. (e) Determine the end behavior f (x) - as x - -co and f (x) - as x - co 7.
