Answer:
The maximum value of the equation is 1 less than the maximum value of the graph
Step-by-step explanation:
We have the equation .
We can know that this graph will have a maximum value as this is a negative parabola.
In order to find the maximum value, we can use the equation
In our given equation:
a=-1
b=4
c=-8
Now we can plug in these values to the equation
Now we can plug the x value where the maximum occurs to find the max value of the equation
This means that the maximum of this equation is -4.
The maximum of the graph is shown to be -3
This means that the maximum value of the equation is 1 less than the maximum value of the graph
