Answer:
• y-intercept = (0, 0)
,
• Vertex = (1/2, 5/4)
,
• Axis of symmetry = 1/2
Step-by-step explanation:
Given the function:

The vertex is:

Substitute 1/2 into the given function to find the y-coordinate of the vertex

Therefore, the vertex is (1/2, 5/4)
Axis of symmetry:
This is -b/2a

The y-intercept is (0, 0)
