8. The percent p a stock price has fluctuated in one year can be modeled by p(x) = 0.0005x¹-0.0193x³ +0.243x² - 1.014x + 1.04, where x is the number of months since January. a. Use a graphing calculator to graph the function. b. State the relevant domain and estimate the range c. Use the graph to approximate the y-intercept. Then find the y- intercept algebraically. What does the y-intercept represent? d. Find and interpret any zeros of the function.
