Given the parabola equation 
, what is the max or minimum, and where?
Given the parabola equation
The parabola is in the form: 
The vertex formula will determine the x-value of the max or min. Since the value of 
is negative, the parabola will open downward, and there will be a maximum.
Write the vertex formula and substitute the correct coefficients.
Substitute this value back in the parabolic equation to determine the y-value.
The answer is:
