To determine x intercept, we'll put y = f(x) =
0.
But f(x) = x^2-3x+1 => x^2-3x+1 =
0
We'll apply quadratic
formula:
x1 = [3+sqrt(9 -
4)]/2
x1 = (3+sqrt5)/2
x2 =
(3-sqrt5)/2
The x intercepts are: ((3+sqrt5)/2 , 0) and
((3-sqrt5)/2) , 0).
To determine y intercepts, we'll cancel
the x coordinate.
f(0) = 0^2 - 3*0 +
1
f(0) = 1
The y intercept is
(0 , 1).
The x intercepts are ((3+sqrt5)/2 ,
0) and ((3-sqrt5)/2) , 0) and the y intercept is (0 ,
1).
