(b)
To graph: The function
(b)
Explanation of Solution
Given information:
Graph:
The function
The x -intercepts are
The axis of symmetry is
Now, we plot the axis of symmetry
Then, we find the vertex.
The x -coordinate of the vertex is 1. To find the y -coordinate of the vertex, we substitute
So, the vertex is
Now, we draw a parabola through the vertex
