Answer: A) max of equation is less than max of graph
Step-by-step explanation:
"Max" refers to the greatest y-value (vertex)
The given graph has a max of -3.
Equation: y = -x² + 4x - 8
a=-1 b=4
Axis of Symmetry is: [tex]\dfrac{-b}{2a}=\dfrac{-4}{2(-1)}=\dfrac{-4}{-2}=2[/tex]
Max is: f(2) = -(2)² + 4(2) - 8
= -4 + 8 - 8
= -4
The max of the equation is -4
The max of the equation is one less than the max of the graph.
