Answer:
• The minimum value of the graph is y=-8.
,
• The axis of symmetry is x=2
Explanation:
On examining Josie's steps, she did not make a mistake.
In the function, f(x):
[tex]f(x)=x^2-4x-12[/tex]
The coefficient of x² is positive, therefore, the graph has a minimum.
From the vertex, (2,-8):
• The minimum value of the graph is y=-8.
,
• The axis of symmetry is x=2
