Answer: A) max of equation is less than max of graph

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:
(-b)/(2a)=(-4)/(2(-1))=(-4)/(-2)=2

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.
