.
Axis is symmetry = -b/2a = -(-2)/2(3) = 2/6 = 1/3
x = 1/3
.
Vertex is point on the axis of symmetry defined by x=1/3
y = 3(1/3)^2 - 2(1/3) + 1
y = 3/9 - 2/3 +1
y = 3/9 - 6/9 + 9/9
y = 6/9 = 2/3
(1/3, 2/3)
.
y-intercept occurs when x=0, which is 1.
.
The equation does not factor, so the quadratic equation may be tried.

.
For these solutions to exist, the discriminant b^2-4ac should not be a negative number.
.
In this case the discriminant is -8. That means that there are no solutions among real numbers.
