Answer:
The vertex of the function is (3,0).
The y-intercept is (0,4.5).
Explanation:
Given : Function

To find : Identify the vertex and the y intercept of the graph of the function?
Solution :
The given function is a equation of a parabola.
The equation of a parabola in vertex form is

where (h, k) are the coordinates of the vertex and a is a multiplier
On comparing with given equation,
h = 3 and k = 0,
So, The vertex of the function is (h,k) = (3,0)
To find the y- intercept,
Put x = 0 in the function,



So, The y-intercept is (0,4.5).
