You can determine this by doing b² - 4ac (using the values in the quadratic function) and see if it is greater than zero, less than, or equal to. If it is greater, then it has 2 x-intercepts or zeroes. If it equals zero, then you have one x-intercept. If it equals less than zero, you have no x-intercepts.

Step-by-step explanation:
Given the data ;
Year Period Users (Millions)
2004 1 1
2005 2 5
2006 3 11
2007 4 58
2008 5 145
2009 6 359
2010 7 607
2011 8 846
A quadratic regression model can be obtained using a quadratic regression calculator ; The quadratic regression modeled obtained is in the form :
y = Ax² + Bx + C
y = 26.3x² - 116.9x + 109.6
