Explanation:
Given the function:
First, we find the vertex of the parabola.
Vertex
The equation of the axis of symmetry is calculated using the formula:
From the function: a=2, b=-12
Substitute x=3 into y to find the y-coordinate at the vertex.
The vertex is at (3, -3).
Two points to the left of the vertex
When x=2
When x=1
Two points to the right of the vertex
When x=4
When x=5
Answer:
Plot these points on the graph: (3, -3), (2,-1), (1,5), (4,-1), and (5,5).
