Find the vertex of the function. Write your answer in the form (x,y). Use the slash mark as a fraction bar if necessary.
That is with Calculus. Now in Algebra, do this
y=x^2-x + xxxx -23-xxxxx
we are going to make a difference of prefect squares.
y= (x-1/2)^2 - (sqrt22.75)^2
so clearly, this is a minumum at x=1/2
