Hi

f(x) = x^2 - 3x + 1   |y-intercept when x = 0  Pt(0,1)

   x^2-3x + 1 = 0        |x-intercept when f(x) = 0  

Note: General format  ax^2 + bx + c = 0

x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+

 x+=+%283+%2B-+sqrt%28+5+%29%29%2F%282%29+

   x = (3+sqrt(5))/2 and x = (3-sqrt(5))/2

Pt( 2.6180,0) and Pt(0.382,0) the x-intercepts
