Answer:
The vertex of the quadratic equation is the point (4,2)
Step-by-step explanation:
we know that
The figure show a vertical parabola open downward
The vertex represent the maximum point of the graph
Looking at the graph
The maximum point of the graph is (4,2)
therefore
The vertex of the quadratic equation is the point (4,2)
see the attached figure to better understand the problem
The above expression is not in its simplest form, and we need to simplify it, that is what asked in the question.
Given equation,
First of all, let's open the parentheses to combine the like terms for simplifying.
Arranging the like terms, x² with x², x with x and constant terms near to each other.
Simplying further,
So, the correct option is C
