How do you find the vertex and intercepts for y = 2(x - 3)^2 + 1?

This is already in vertex form making it easy to identify the vertex ...

Explanation:

vertex form: y=a(x-h)^2+k, with vertex (h,k)

vertex =(3,1)

The vertex is above the x-axis and since the coefficient a=2 is positive, this parabola opens upward and will have no x-intercepts (only 2 imaginary roots).

The y-intercept happens when x=0

y(0)=2(3^2)+1=19

hope that helped
