The equation is,
The general equation of parabola with vertex (h,k) is,
On compare the equation of parabola with general equation, the values are a = 2, h = 3 and k = 1 , the vertex of parabola is (h,k). So vertex of parabola is (3,1).
The value of a is more than 0, means parabola open upward so vertex correspond the minimum value. Minimum value is 1 for x = 3.
The parabola vertex is (3,1) and axis of symmetry for parabola is x = h. So axis of symmetry is x = 3.
Substitute 0 for x in equation to obtain the y-intercept of function.
So y-intercept is (0,19).
Plot the equation on the graph.
