Find the equation of the axis of symmetry for the graph of y=x^2-7x+12 , and state whether the axis of symmetry contains a maximum point or a minimum point of the graph.
:
There is a simple equation to find the axis of symmetry of a quadratic equation
x =
:
In your equation a = 1, b = -7, c = 12, (not needed here)
x = ; a minus a minus, is a plus
:
x = or +3.5 is the axis of symmetry
:
A simple rule to know if it has a maximum or a minimum
If the coefficient of x^2 is positive, it has a minimum
If the coefficient of x^2 is negative, it has a maximum
:
It looks like this:

:
Note that the axis of symmetry is +3.5 and it has a minimum
